Many of you asked me to provide the most Optimized Settings for PC Gaming for a very long time, so (with the launch of Starfield) I finally decided to dig deep into the PC optimization void and, after months of research and direct testing, here's my complete guide and suggestions for it.

The goal is to noticeably increase average FPS (incl. 1% lows), stabilize Frame Time, remove micro-stutters, decrease input lag, properly setup HDR and all without noticeably sacrificing quality.

My direct testing and focus was on Windows + NVIDIA Control Panel + In-Game + HDR settings, but you can also find AMD Control Panel optimized settings as well.

I will also try at best to explain very technical/difficult names and features in the simplest yet effective way possible for most people to better understand what exactly each setting/change is doing and why it was changed accordingly.

I will avoid "risky" third-party tools or de-bloaters which may permanently harm your system as well.



Essential first steps:

  • Use Windows 11 22H2 or newer and make sure to be fully up-to-date running Windows Update multiple times (and Reboot if necessary) until no more updates are being prompted;
  • Windows Update will generally also update most drivers for your PC, but after you're done with it I highly recommend to also manually double check for your device drivers' updates on your OEM website or from dedicated App (e.g. Lenovo Vantage) (if you have a laptop or pre-assembled PC) or if you have a custom built PC go update GPU drivers directly from NVIDIA or AMD websites;
  • Make sure all your installed Games are also up-to-date with their latest patches.


Windows 11 "Safe De-Bloating"

These steps will contribute in having the most lightweight version of the OS (which will contribute in stabilize the frame time and fix stuttering in games) without compromising its stability:



1.webp


  • Go to Settings -> Apps -> Apps & features and Uninstall all unnecessary/unused applications from your system (by clicking the 3 dots on the right for each app)
  • Only use Windows Defender. Avoid installing/using any other third-party Anti-Virus software (so also uninstall them if present and then Reboot)




2.webp


  • Use the free O&O ShutUp10++ tool to disable most of Windows 11 telemetry and background "spying" processes by following this guide




3.webp


  • Press Ctrl + Alt + Del to open Task Manager -> Go to Startup Apps section -> Disable all unnecessary Startup apps




4.webp


  • Use Chris Titus Windows Utility: Search for "Windows PowerShell" in the Taskbar and Open it as Administrator, then run the following command (you can copy/paste it):

    iwr -useb https://christitus.com/win | iex

    This will open the latest, online version of the great free Chris Titus Utility Scripts (if it prompts to install Chocolatey, do so) you can use to rapidly adjust new installations of Windows in a very safe and automatic way (if you know what you're doing).
    So go directly to the "Tweaks" tab and select exactly what you see in the preview image above, then click "Run Tweaks" and wait for the scripts to finish (in the separate PowerShell window), then you can close the utility




  • Clean your system and check for its integrity using in-built Windows tools by following this guide and Reboot your machine




Windows 11: Optimized Settings

Now that you have a slimmed, stable and efficient Windows 11 OS, it's time to configure it at best for gaming.



6.webp


  • If you're using a Laptop, plug it to the AC Power: even if everyone should already know it, please don't game on battery and pretend good performance at the same time...
  • Use the Balanced power plan: on Settings -> System -> Power section. Contrary to what people usually suggest (switching to High Performance plan), the Windows 11 Balanced Power plan provides identical if not higher average FPS (incl. 1% lows) in all games I've tested so far along with ensuring that CPU is working at max only when needed, therefore making it more efficient both for everyday tasks and gaming. That said, if you're using a Laptop where the OEM also created additional Power profiles options (e.g. Lenovo "Intelligent Cooling" vs "Performance" profiles), you should use its maximum performance profile when gaming instead (e.g. changing it in the Lenovo Vantage app or using its keyboard shortcut to rapidly change it to "Performance" before gaming and returning to "Intelligent Cooling" after)


xDTnfPs.png


  • Disable Core "Parking" and "Frequency Scaling" (only when Plugged In to AC) with ParkControl: which you can download for free here. By disabling those, coupled with also setting "Heterogenous Policy" to "Standard Parking" and "Short + Long Threads" to "2: Prefer performant processors" you will noticeably improve frame times and remove most if not all stutters in all games (especially the most CPU demanding). You can leave the "On Battery (DC)" section to its default settings and then just make sure the program is starting with Windows



7.webp


8.webp


  • Use your display Native Resolution + Max Refresh Rate (as main): for example if you connected your PC to an LG OLED, from Windows 11 System -> Display section set its Resolution to 3840x2160, 200% Scale @ 120hz Refresh Rate. Then make it the "main" display as shown in the image above




9.webp


  • Enabled all the new Windows 11 graphics features: from Settings -> System -> Display -> Graphics -> Default graphics settings. Those combined will provide lower latency and better compatibility with newer games and features (see more in the the next section for NVIDIA)




10.webp


  • Always enable HDR before gaming + use Auto HDR (or disable it if you use RTX HDR): in the System -> Display -> Use HDR section. This is VERY important.
    Considering many native HDR games won't even trigger to HDR if the system "Use HDR" option is disabled, it's best to be sure that the setting is always enabled before launching any game.
    This way: native ones will always correctly handshake to HDR10 while SDR ones will be auto-converted to a good Native HDR10 presentation thanks to the AutoHDR or RTX HDR in a similar way Xbox Series do as well.
    In this section you can also tweak "SDR content brightness" which I recommend to be set to 35 (which will correspond to 250 nits)
    If you don't want to manually re-enter this section to enable/disable the Use HDR toggle each time before gaming, you have two options:
    1) Always use HDR even for Windows (Recommended)
    2) Use this shortcut to quickly toggle between "Use HDR: On/Off" before/after using a game: Win + Alt + B




11.webp


12.webp


  • Download and install the new Windows HDR Calibration app (from Microsoft Store): make sure "Use HDR" is On, then Open it and start configure it in very similar way to the Xbox and PS5 HDR Calibration apps and suggestions. Basically:

    -Always set the black "Maximum Luminance" (first section) to 0 (leftmost);
    -Set the subsequent two white "Maximum Luminance" sections the same, depending if you're using HGIG or not on the TV (e.g. if HGIG on LG OLEDs: 800 nits for all except G2 to 1.000 nits and G3 to 1.500 nits. While if not using HGIG but Dynamic Tone Mapping instead: set those two slider to 4.000 nits or Max value if you can't reach those nits);
    -Leave the last "Color Saturation" section to Less (Default), at the leftmost position.

    Once you've done, you can give a name to the calibrated profile for your Display/TV and save it. This will remain associated to it and be used by all supported native HDR games + all Auto HDR and RTX HDR games as well




13.webp


  • Be sure Game Mode is enabled: in Settings -> Gaming -> Game Mode. This will ensure that every time you launch a game, many Windows 11 background tasks will be automatically halted and/or reduced in priority to allow a less stuttery, more consistent gaming experience. Everything will be back to normal when you exit the game




NVIDIA Control Panel: Optimized Settings

With Windows 11 ready to go, it's time to move to NVIDIA Control Panel specific optimizations which, as introduced in the guide, aim to increase as much as possibile the in-game performance while providing the best stability/consistency at the lowest input lag possible, all without noticeably sacrificing quality:



14.webp


  • Enable G-SYNC: for the previously setup main display you will use for gaming (e.g. LG OLED). If you're not able to do so, first verify VRR & G-Sync is also enabled on the Display itself. G-Sync (or NVIDIA's proprietary Variable Refresh Rate technology) will ensure consistently smooth gameplay even when the game framerate is unstable and/or is unlocked.
    Use the "Enable for full screen mode" option for best compatibility and stability while remembering to also set games to "Full Screen Mode" or even better to "Borderless Window" (which will have even lower input lag now) in their in-game settings whenever possible (see the next In-Game settings section for more info)




15.webp


  • Use your display Native Resolution + Max Refresh Rate (again): also in NVIDIA CP -> Display -> Change Resolution section. For LG OLEDs I also recommend to manually use RGB Output color format, Highest (32-bit) color depth, 10 bpc Output color depth at Limited Output dynamic range. If you use your PC also for movies and media consumption, avoid PC Mode / HDMI input icon on the TV for the reasonings you can find here and here , otherwise you can use PC Mode for reduced input latency with any TV preset in use (but with locked Clarity options which may be detrimental for movies)




16.webp


  • Use the "No scaling" + "GPU" combo: in the Display - Adjust desktop size and position section. This will ensure the lowest latency I've measured in all games I've tested so far. Just remember to also set games to match your Native Display Resolution set above.
    If after the change you're seeing black bars or a strange 4096x2160 native resolution on some 4K/HDR TVs (e.g. LG C1 OLED), it's a known bug: follow these steps to fix it by manually removing the exotic resolution and restore the proper/native/standard 3840x2160 (4K) resolution




17.webp


Now it's time to setup the "good stuff".

  • Go to 3D Settings -> Adjust image settings with preview and select Use the advanced 3D image settings, then click Take me there


18.webp


Here you can find a complete list of both "Global" and "Program" settings. As those names suggest, the first sheet will apply the selected settings to ALL programs and games while (after) you can manage eventual differences for specific program/games for which you desire/need to change specific values for them only.



I will now provide my full list of Global Optimized Settings below, along with the reasonings behind each setting:



Image Scaling/Sharpening: Scaling/Sharpening Off

This is basically an old method of upscaling lower-res contents to native resolution which was vastly superseded by DLSS 2.5.1 and higher, which is highly recommended instead



Ambient Occlusion: Off

This setting is best to be left for the game itself to be managed or you may noticeably lose performance if forced at driver level



Anisotropic Filtering: Application-controlled

Even if 16x AF for all games is a good idea as the visual improvements to textures' definition on medium-long distances is big with a very little if zero performance cost, forcing it at driver level may create textures issues with some games (e.g. Starfield) so it's better to manage this setting directly in-game (when available)



Anti-Aliasing - FXAA: Off

This setting is best to be left for the game itself to be managed or you may noticeably lose performance if forced at driver level



Anti-Aliasing Gamma Correction: Off

No need. It is already controlled by game



Anti-Aliasing Mode: Application-Controlled

This will ensure AA will be directly controlled by games, which is what you want. When using DLSS (highly recommended) there's no need to also separately enable AA in-game as AA is included in all DLSS profiles during the upscale



Anti-Aliasing Setting: Application-Controlled

This will ensure AA will be directly controlled by games, which is what you want. When using DLSS (highly recommended) there's no need to also enable AA in-game as AA is included in all DLSS profiles during the upscale



Anti-Aliasing Transparency: Off

No need. It is already controlled by game



Background Application Max Framerate: Off

If you're an avid "multitasking" user which often switches between a game and other PC tasks, you can set it to 20 to be sure the game isn't tanking your regular Windows performance, but nowadays the new "Borderless Window" mode makes it unnecessary. Leave it Off



CUDA - GPUs: Select your most powerful GPU

If you have multiple GPUs on your system (e.g. iGPU + dGPU in a Laptop), make sure to select only the most powerful GPU (e.g. dGPU) here in order to leverage CUDA processing more efficiently



CUDA - Sysmem Fallback Policy: Prefer No Sysmem Fallback

This will ensure that games' assets/textures only get loaded in faster VRAM, improving performance, but with the only drawback to crash the game if VRAM is not enough. If this is often the case, try lowering the game graphics' options (for example starting with using a lesser DLSS tier like from Quality to Balanced or Performance) to reduce VRAM usage



DSR - Factors: Off

This is basically Supersampling. It could be useful if you have a 1080p or 1440p monitor along with a very powerful GPU (e.g. which can easily manage to run games at 4K/60fps and above). How? You can for example enable it (along with all multipliers inside the setting) and then select the 1440p (2560x1440) or 4K resolution (3840x2160) respectively + enable DLSS: Quality or Balanced in-game to have a better than native 1080p or 1440p image + TAA and also better performance with it at the same time. If you're already using a 4K Display, leave it Off



DSR - Smoothness: Off

If you enabled DSR - Factors, set this to 33%



Low Latency Mode: Ultra

Basically you will have much lower input lag and also the advantage of games auto-capping their framerate 3-4 frames less than the selected Refresh Rate (e.g. 116 fps cap on a 120hz Refresh Rate), ensuring G-Sync is working at best without any visible screen tearing or stutters.
When NVIDIA Reflex is enabled in-game this will automatically bypass Low Latency Mode so that the two options are not conflicting.



Max Frame Rate: Off

Even if ideally this should be manually set to 3-4 frames less than the used Refresh Rate for DX12 games without Reflex support, in reality capping the framerate when using G-Sync will increase stuttering. V-Sync + G-Sync alone will work better even in those cases (see the V-Sync description below)



Monitor Technology: G-SYNC

Select this to make sure G-Sync is working properly with the selected main display



Multi-Frame Sampled AA (MFAA): Off

This setting will improve MSAA when selected in-game, but is not necessary when using DLSS as this already incorporates an AA solution in it so, when enabled, this setting could cause flickering issue together with DLSS



OpenGL GDI Compatibility: Auto

This will ensure the max compatibility with both older and new games. No need to change it



OpenGL rendering GPU: Select your most powerful GPU

If you have multiple GPUs on your system (e.g. iGPU + dGPU in a Laptop), make sure to select only the most powerful GPU (e.g. dGPU) here in order to leverage a more efficient rendering



Power management mode: Normal or Optimal Power

Similarly to the the Windows 11 Balanced Power Plan suggestion, there is no need to always have the GPU at max usage all the time (it could even hurt the performance by becoming hotter and then getting downclocked) so this setting will ensure the GPU will only be maxed out when needed in a more efficient way



Preferred refresh rate: Highest available

This will ensure correctly leveraging G-Sync



Shader Cache: 10GB

After additional analysis, this value will provide the same performance of "Default" setting (which will be equal to 4GB) for 95% of games...but for the heaviest games out there (e.g. Star Citizen, Flight Simulator) it will noticeably reduce random shader compilation stutters.



Texture Filtering - Anisotropic sample optimization: Off

This setting aims to reduce Anisotropic Filter quality to improve performance, but considering how small 16x AF impact is it's really not necessary, especially considering it can also cause flickering issues when using DLSS



Texture Filtering- Negative LOD bias: Allow

This will allow games to increase performance by rendering LOD closer to the player. Many games may stop working properly if set to "Clamp" and also DLSS could cause severe flickering issues with "Clamp". Leave it to Allow



Texture Filtering - Quality: Quality

This will ensure 16x Anisotropic Filtering quality when selected in-game, but also making the next option available to be changed



Texture Filtering - Trilinear optimization: On

Trilinear optimizations are aimed to make 16x Anisotropic Filtering more efficient, improving its performance a bit without losing quality at all nor causing issues with DLSS, so you can leave it On



Threaded optimization: Auto

If you have a powerful, multi-core CPU along with a good GPU, this settings will help in GPU-bound situations where CPU multi-cores + multi-threading may help in keeping the performance high. If you have an under-specs' CPU (e.g. an old dual-core only) you can try setting this to Off and see if performance in games will improve for you



Triple Buffering: Off

This is very important to be disabled both here at driver level and in-game level when using G-Sync or it may cause FPS drops and stuttering



Vertical Sync: On

This is very important to be enabled at driver level AND disabled at in-game level when using G-Sync as with G-Sync this is not real V-Sync, but (together with Low Latency Ultra and/or NVIDIA Reflex) this will ensure the variable FPS in games will always be matched to the Variable Refresh Rate of the Display but always up to -3/4 fps the max Refresh Rate (to always have the lowest input lag and no tearing)
In DX12 games without Reflex support V-Sync will actually trigger only when FPS is higher than used Refresh Rate to eliminate tearing but will automatically disable itself when FPS go back under the Refresh Rate, preserving smoothness and low input lag


Virtual Reality Pre-Renderes Frame: 1

That's default for VR headsets, so leave it alone even if you don't have one



Virtual Reality - Variable Rate Super Sampling: Adaptive

Also for VR headsets only, but you can set it do Adaptive to improve VR performance at no noticeable quality loss



Vulkan/OpenGL present method: Prefer layered on DXGI swapchain

This will enable Borderless Fullscreen advantages of Windows 11 also for Vulkan and OpenGL games while also including better G-Sync and Auto HDR support for them. If you encounter issues with specific games (e.g. flickering) you can revert to "Auto" just for them



DNfY6PP.png

  • Enable RTX video enhancements (Super Resolution: Auto + High Dynamic Range): under NVCP Video section. This will noticeably improve low-res video upscale + introduce a very good "AutoHDR" upscale also for SDR videos


qOyBK7n.png

  • Enable RTX HDR instead of Windows AutoHDR: for a much better SDR-to-HDR AI upscale (with correct black levels, much less color banding, better contrast and higher peak brightness) for ALL SDR games. You can enable it officially by using the new NVIDIA App but actually it's not necessary to install it. You can just use NVIDIA Profile Inspector + adding this XML file to its folder before launching it and then configure it as the image above (for LG G3 OLED only use these), click "Apply changes" and reboot. RTX HDR will have a noticeably hit to performance by default (around -10%) but activating the above flag "Enabled (Low Quality (0x06)" the cost for it will lower to around -3% with no visible differences compared to default and, trust me, it is definitely worth it over Windows AutoHDR (which you also need to disable if you want to use this).
    If some of your native HDR10 games will have washed out colors after the change, set "Enable TrueHDR Feature" flag to Off only for them (through NVIDIA Profile Inspector or disable RTX HDR only for them in NVIDIA App).



Apply all settings and reboot your PC









AMD Control Panel: Optimized Settings

While I did not test and verified myself the AMD Control Panel optimizations, after a bit of searching I think the following one is the most comprehensive and thought out optimization guide you can find for it, so go have a look




View: https://www.youtube.com/watch?v=oltTkFODy8w








PC In-Game Settings: Optimized

If you came this far and applied all the previous optimized settings for both Windows & NVIDIA/AMD Control Panel, just remember to always change the following in-game settings for PC games:


  • Use "Borderless Fullscreen/Window" mode whenever possible otherwise use "Full Screen" mode (to work best with both G-Sync/Freesync, Low Latency Ultra and NVIDIA Reflex)

  • Always use native Display Resolution @ Highest Refresh Rate: e.g. 3840x2160 (4K) on LG OLEDs @ 120hz

  • Disable V-Sync: as this is already enabled at driver level (and working differently for G-Sync/Freesync, Low Latency Ultra and NVIDIA Reflex)

  • Disable Triple Buffering and Double Buffering: as those settings will cause issues (with G-Sync/Freesync, Low Latency Ultra and NVIDIA Reflex)

  • Disable any Frame Rate Cap: as G-Sync/Freesync + V-Sync (at NVIDIA driver level) + Low Latency Ultra and NVIDIA Reflex will already cap your FPS to up -3/4 fps your actual Refresh Rate automatically, so no need to add others FPS limiters. In DX12 games without Reflex support the NVCP V-Sync will automatically eliminate tearing if FPS goes above the Refresh Rate and automatically disable itself under

  • Always enable NVIDIA Reflex set to "On": whenever available. Similarly but even better than Low Latency Ultra (and also an automatic replacement of it), this will noticeably decrease input lag, improve frame time consistency and also automatically guarantee G-Sync is always working as intended (below your set Refresh Rate). The "+ Boost" added feature will not allow GPU to downclock itself while using the game, which may have a little more consistent input latency but at expense of considerably higher power usage/temps and some reported average FPS drops, so it's better to keep Reflex without Boost for the majority of users and cases

  • Set Anisotropic Filtering also to 16x: whenever available

  • Always use DLSS2+ Super Resolution: this is one of the most important setting to ALWAYS enable considering that, in all cases I've tested, the "Quality" and "Balanced" presets provided better than Native and almost equal to Native picture and motion respectively with much higher average FPS (incl. 1% lows), much better Frame Times and even less VRAM consumption thanks to hardware accelerated AI Image Reconstruction.

    Really, it's almost like Voodoo magic.
    For the best quality/performance balance I also suggest to:
    -Use DLSS Balanced with 4K Display Resolution (but switch to better or faster presets if needed)
    -Use DLSS Quality with 1440p or 1080p Display Resolution (but switch to better or faster presets if needed)

    I also recommend simply swapping/overwriting DLSS Super Resolution .DLL in game folders (after doing a backup first) to the the latest official .DLL version you can find here and then force the "Preset E" for it (which will have no ghosting, no oversharpening and a crisp and temporally stable upscale with less VRAM usage. It only requires DLSS v3.7.0 and above) by using NVIDIA Profile Inspector + adding this XML file to its folder before launching it and then configure it as follows for the global profile (all games). This method will also make using mods as "DLSSTweaks" no more necessary and also preserve online multiplayer without getting banned:

    l9gdocb.png


    If NVIDIA DLSS2+ is not supported in the game but AMD FSR2+ is, use this one with the same suggestions (it will be a bit less efficient, but still worth it)

  • Evaluate if also adding DLSS3+ Frame Generation on top: this is another way to almost double your average FPS by adding hardware-accelerated AI Motion Interpolation to what you already achieved up to now, but differently than DLSS2+ Super Resolution, this will not further lower your input lag but the opposite, it will increase it again a bit (but may be unnoticeable thanks to NVIDIA Reflex being forcefully enabled with it). Furthermore, another disadvantage may be the introduction of motion artefacts (as ghosting, UI/HUDs flickering) especially if the base FPS you're trying to double are too low (usually sub-50fps). So my advice is to first try it mainly for non-competitive games and/or games with Ray Tracing enabled as well. If you don't notice any severe artefacts you can keep it On, otherwise disable it

    I also recommend simply swapping/overwriting DLSS Frame Generation .DLL in game folders (after doing a backup first) to the the latest official .DLL version you can find here

    If NVIDIA DLSS3+ Frame Gen is not supported in the game but AMD FSR3+ Frame Gen is, use this one with the same suggestions (it will be a bit less efficient, but still worth it)

  • Always use the new DLSS 3.5+ Ray Tracing Reconstruction: whenever available for Ray Traced games. This will basically improve Ray Tracing through hardware accelerated AI RT Reconstruction at the same performance cost, if not a bit lower

    I also recommend simply swapping/overwriting DLSS Ray Reconstruction .DLL in game folders (after doing a backup first) to the the latest official .DLL version you can find here


  • Force enable ReBAR for all games: follow the instructions of this video to enable ReBAR both on your BIOS (if compatible) and NVIDIA Profile Inspector for all games. After testing 25+ games, I measured an FPS boost of around 5% both for Average FPS and 1% Lows when enabled as the image below. If a game is not working correctly after the change (e.g. Ratchet & Clank Rift Apart crashing the Desktop as soon as you quit it) you can disable ReBAR just for that game with NVIDIA Profile Inspector.

    HvEnvqB.png

  • Use my suggested in-game HDR settings for your TV: you can find over 200+ personally tested in-game calibrated HDR settings here , on my Patreon "About" page and Index. Many are accessible to everyone for free, but for the others I kindly ask you to support my work as I usually need to buy those games at full price for providing updated settings at D1 release or near. Thank you! 🙏🏻






LG OLEDs: Optimized Settings
LG-G3-oled-2023.png


With the entire PC (Windows 11 + NVIDIA/AMD Control Panel + In-Game Settings) configured as suggested, you can then finally use the:




[4K/HDR] Optimized Gameplay
(YouTube Playlist)

Here you will find Very High Quality (among the best seen on YT), Direct-feed gameplay recordings in Native 4K, 60fps, color-accurate and Calibrated HDR after applying all the optimizations in this guide to my new PC (Full Specs and Setup in each video description)

For this reason, I highly recommend to see them from a true HDR display!

YouTube will still decently tone map them to SDR automatically if you can't.

I will periodically add new gameplay recordings for select games over time, so if you like them please support my work by leaving a Like & Subscribe on the YouTube channel and on Patreon!


NOTE:
In order to preserve the highest and smoothest quality of the recordings, the actual performance you see is around 5-10% slower than normal. Just consider that as a reference if you want to compare it with similar setups.



Let me know in the comments what improvements you had after all these optimizations (if any) and generally if you found them useful or not.



Enjoy :)

Thanks!
In the meanwhile you can still apply all other suggestions (Win11, HDR, In-Game) while trying to mimic what I did in the NVIDIA CP with AMD CP as well (taking account of its different naming), but I'll work on that too

Most of this stuff is fine, but I would recomend most people skip the Chris Titus utility unless you really understand what it does. Better off just going through and uninstalling stuff you dont need through windows settings. Also when using O&O shutup only use reccomended/safe setting nothing else.

Came here to post this as well. These third party tools that disable parts of OS for "performance benefits" are a terrible idea. They are enabled for a reason, and it's not because Microsoft wants to intentionally slow you down.

It seems the most comprehensive and thought out to me so far.
I will also add it to the article.

Never had a problem with the shutup tool as long as you use reccomended setting, it doesnt do anything too crazy. But yeah for the most part you are right about the third party tools/optimizer garbage.

I appreciate the idea behind a simple guide. I used to be using no latency mode and no vsync in NVIDIA control panel because that is what used to be recommended and I had a hard time understanding why I was still getting tearing with gsync

Most of this stuff is fine, but I would recomend most people skip the Chris Titus utility unless you really understand what it does. Better off just going through and uninstalling stuff you dont need through windows settings. Also when using O&O shutup only use reccomended/safe setting nothing else.
Yeah, I also mentioned in the guide, but just opening it, going to Tweaks tab and applying/running the tweaks shown in the my preview image only should be safe and good for most people.

The problem with PC gaming is that there's not a "one size fits all" fix for performance issues. What works for one game might not work for another because of how that game addresses memory or CPU differently from the previous one.

At best, it's placebo effect and at worst, like mentioned earlier, you're disabling important low-level security features that are there for a reason, and it's never worth the trade-off even in the rare chance that the change actually does something.

What performance boils down to in 99% of cases is "tweak the in-game settings until performance is where you want it".

I think the issue is people read these guides and blindly turn off things that most people should leave alone. Having a bunch of people turning off important security features is not a good idea. Sure it might be fine for you, but everyone shouldnt be doing it.

I'm reluctant to post corrections, since this is on your patreon rather than a post here.
If you have an HDR display, I would recommend leaving it enabled on the desktop rather than toggling it per-game, or expecting the game to switch it.
One of the nice things about Windows 11 is that you should basically never have to deal with display mode switches any more.

Enable G-SYNC: for the previously setup main display you will use for gaming (e.g. LG OLED). If you're not able to do so, first verify VRR & G-Sync is also enabled on the Display itself. G-Sync (or NVIDIA's proprietary Variable Refresh Rate technology) will ensure consistently smooth gameplay even when the game framerate is unstable and/or is unlocked.
Use the "Enable for full screen mode" option for best compatibility and stability while remembering to also set games to "Full Screen Mode" in their in-game settings whenever possible (see the next In-Game settings section for more info)
As you say, G-Sync should always be set to full screen mode only.
gsync-ytd4v.png

The "windowed and full screen mode" option is a 'hack' into the DWM to try and make g-sync work in borderless/windowed games, but it never worked correctly.
It would not sync to the correct rate in most games, and would often be enabled on desktop applications which were not games - dropping the refresh rate to single digits until you moved the mouse.

But Windows 11 fixes this.
They added "optimizations for windowed games" which upgrades them to use flip-model presentation.
That enables borderless/windowed games to work with the "full screen mode" g-sync.

With few exceptions, there is no need to run games in fullscreen exclusive mode any more on Windows 11.
Now some games do have a distinction between "fullscreen" and "fullscreen exclusive" mode, but if I was making a recommendation, it would be to use borderless or "fullscreen window" mode.

Note that it is also important to have games marked as such in the Game Bar settings now.
Most games should be detected automatically, but newer games or indies may not be. I'm not sure exactly how it determines what is a game or not.
gamebar-49fsu.png


This sets an appropriate performance profile in Windows and helps keep the refresh rate locked to the game's frame rate.
For example: when you change the volume level and that pop-up overlays the game image.
Without being marked as a game, this will temporarily cause the refresh rate to jump up to its maximum. When marked as a game, it should be seamless (assuming MPOs are enabled and working on this display).

Use the "No scaling" + "GPU" combo: in the Display - Adjust desktop size and position section. This will ensure the lowest latency I've measured in all games I've tested so far. Just remember to also set games to match your Native Display Resolution set above.
GPU scaling does not add latency.
It should be set to whatever you prefer, and the override should be enabled - because a handful of games do specify scaling modes (sometimes the wrong modes).
If I recall correctly, MGSV: Ground Zeroes was one of them.

Image Scaling/Sharpening: Scaling/Sharpening Off
This is basically an old method of upscaling lower-res contents to native resolution which was vastly superseded by DLSS 2.x and higher, which is highly recommended instead
This is the newer scaling/sharpening option for NVIDIA GPUs, which uses NIS.
The "Adjust desktop size and position" options use the old bilinear(?) scaler.

However, it should not be enabled.
Enabling this prevents the use of multi-plane overlays (MPOs) which are required for borderless/windowed-mode VRR to work properly on Windows 11.

Now it's time to setup the "good stuff".
  • Go to 3D Settings -> Adjust image settings with preview and select Use the advanced 3D image settings, then click Take me there
I'm not going to go into every single option here.
But many of these recommendations are wrong. Why would you disable gamma-correct MSAA, for example?

Nearly all of these settings should be left at the NVIDIA defaults.
Forcing Anisotropic filtering to 16x can have a noticeable performance impact in bandwidth-heavy games now. It hasn't been 'free' for some time, and modern games are pushing bandwidth a lot more.
Set this in the game, and only override on a per-app basis if there is no option, or if the in-game option is not applied everywhere.

I do not recommend forcing V-Sync via the NVIDIA Control Panel any more.
Doing this can prevent games/applications from specifying the desired mode. It will prevent things like half-rate v-sync, and blocks games from disabling v-sync on loading screens to speed them up.
Sure, that should not be tied to frame rate, but for some reason many games do it.
You should always have v-sync enabled when using VRR, but there is no reason to avoid the in-game option in most cases. You can override it in a per-game profile if required.

Vulkan/OpenGL present method should be set to "Prefer layered on DXGI swapchain."
This uses a small amount of VRAM to enable MPO support in VK/GL applications - allowing AutoHDR and Borderless/Windowed G-Sync to work on Windows 11.

My C1 won't let me pick 12 bpc Output color depth in NVCP
is this right? I have YCbCr444 selected
The C1 has 40 Gbps HDMI 2.1 support, 10-bit is the limit.
12-bit is for 48 Gbps HDMI 2.1 support.

Yeah, in the guide I also mentioned this as a possible solution...but I wouldn't recommend it as Windows, Office and other PC applications will output with wrong/muted colors when always in HDR.
To me, a better workaround is just using Win + Alt + B to enable HDR just before launching a game and then toggle the HDR off system wide when exiting a game.

I also did mention to enable the new W11 flip model in Windows graphics option, but I still found G-Sync working more consistently when set to Fullscreen only.
When enabled to everything it can also cause stutters and weird behavior when just using video players or other regular, "non-game" applications.

Yeah, I already recommend this to be Off.
DLSS is just the better alternative now.


I'm not going to go into every single option here.
But many of these recommendations are wrong. Why would you disable gamma-correct MSAA, for example?
Because MSAA is not needed anymore with DLSS (which includes its proprietary AA solution which can create glitches coupled with MSAA).
If you want to use DLSS: Off (which I would never recommend considering how good it is at Quality, but even at Balanced in 4K) + MSAA, the Gamma Correction is already done by the game itself, no need to have it on driver level.

Nearly all of these settings should be left at the NVIDIA defaults.
I respectful disagree even if, like you can see, I have not changed that much from defaults.

Forcing Anisotropic filtering to 16x can have a noticeable performance impact in bandwidth-heavy games now. It hasn't been 'free' for some time, and modern games are pushing bandwidth a lot more.
Set this in the game, and only override on a per-app basis if there is no option, or if the in-game option is not applied everywhere.
I prefer the opposite reasoning.
16x AF was good on most if not all games I've tried with minimal performance impact, but if you're experiencing issues with specific games you can turn it off just for those games (like I'm already suggesting)

I do not recommend forcing V-Sync via the NVIDIA Control Panel any more.
Doing this can prevent games/applications from specifying the desired mode. It will prevent things like half-rate v-sync, and blocks games from disabling v-sync on loading screens to speed them up.

You should always have v-sync enabled when using VRR, but there is no reason to avoid the in-game option in most cases. You can override it in a per-game profile if required.
I specifically mention V-Sync enabled on driver level works differently coupled with G-Sync + NULL (for DX9-11 games) + NVIDIA Reflex (for DX12 games, which will automatically superseed NULL when enabled).
Even if counter intuitive, this will automatically cap your FPS to -3fps your selected Refresh Rate, which is what you want when using VRR to avoid tearing and stuttering.

Vulkan/OpenGL present method should be set to "Prefer layered on DXGI swapchain."
This uses a small amount of VRAM to enable MPO support in VK/GL applications - allowing AutoHDR and Borderless/Windowed G-Sync to work on Windows 11.
Mmmh, I need to further test this.
Thanks

You should add that low latency mode is per game selection.

Some games have increased fps with it set to on, others with ultra. Sometimes the difference can be around 3-5 fps.
I think it's still the best "set it and forget it" choice as NULL, other than lowering input lag, will guarantee a -3 FPS auto-limiter with your Refresh Rate (for DX9-11 games), so works best with G-Sync.
NVIDIA Reflex will do the same thing (automatically replacing NULL) with DX12 games even if just set to On.

Regarding HDR stuff, reposting from another thread:

1) For brightness slider, values it shows are kinda misleading, as 0 is 80 nits (sRGB default peak white) and every one notch adds 4 nits, so 100 nits is 5, 120 is 10 and so on (assuming you have HGiG on). You want to perceptually match SDR desktop.
2) Fix for washed out windows: https://github.com/dylanraga/win11hdr-srgb-to-gamma2.2-icm. This will also fix black floor in the HDR games mastered / using internally sRGB gamma like CP2077 or RDR2. It will also, however, crush shadow detail in HDR videos and HDR games that already use 2.2 gamma. If you want per game fix you will find it in this reshade shader pack: https://github.com/EndlesslyFlowering/ReShade_HDR_shaders
3) Like Pargon said, you can leave HDR on in windows, and it should be fine. However, if you still want to switch between HDR and SDR per-app basis you can use programs like AutoActions (https://github.com/Codectory/AutoActions) or ColorControl (https://github.com/Maassoft/ColorControl). The latter even allows you to create per app preset for the LG TV, which can be useful when the game doesn't work very well with HGiG and you are too lazy to switch settings manually every time.

I also did mention to enable the new W11 flip model in Windows graphics option, but I still found G-Sync working more consistently when set to Fullscreen only.
Flip-model can be more performant than Fullscreen Exclusive mode.
There's really no need to use it on Windows 11 any more, unless a specific game has issues.

It does a bit and people also benchmarked all the different scaling combinations, with these results:
QDmojaP.png
CUyqa8h.png
This testing would appear to be invalidated by the various display scaling modes somehow producing different results.
If it's being performed on the display, the GPU is not doing anything. Looks like random variance.

Because MSAA is not needed anymore with DLSS (which includes its proprietary AA solution which can create glitches coupled with MSAA).
If you want to use DLSS: Off (which I would never recommend considering how good it is at Quality, but even at Balanced in 4K) + MSAA, the Gamma Correction is already done by the game itself, no need to have it on driver level.
I'm not sure that you understand what this feature is doing. And nearly any game using MSAA will not have DLSS available.
If you don't think it's important, I can't understand why you would suggest disabling it rather than leaving it at the default value. It's a change for the sake of it.

I get it, but like said G-Sync works more erratically when enabled for everything.
With the new DXGI model enabled on Windows graphics options (as already suggested) borderless windows will be treated as Fullscreen btw, so even with G-Sync set to Fullscreen only those will still work correctly with it.

This testing would appear to be invalidated by the various display scaling modes somehow producing different results.
If it's being performed on the display, the GPU is not doing anything. Looks like random variance.
I was able to replicate that via the new NVIDIA input-lag monitoring tool as well, even if the difference was small but was there with No Scaling + GPU, so that's my recommendation.
You can also leverage Integer Scaling for pixel games which will look amazing on a 4K TV.

I'm not sure that you understand what this feature is doing. And nearly any game using MSAA will not have DLSS available.
If you don't think it's important, I can't understand why you would suggest disabling it rather than leaving it at the default value. It's a change for the sake of it.
I never noticed a difference with MSAA Gamma Correction On/Off (maybe a tiny bit less clarity with it On?) when gaming with MSAA enabled (DLSS: Off) and I know that usually devs already implement it at game level, not driver level, therefore I would always keep it Off.
Also, like I said, MSAA is a deprecated AA solution which has been replaced by DLSS or older TAA at least in most games.

Just a note about Dynamic Range, it should be set to "Full" if using a PC monitor and "Limited" only when gaming on a TV. If you're unsure, load up this image and make sure all blocks are distinguishable:

And this, just like so many other things here, is not a "always do this". I have this image up on my LG 4k HDR TV, RGB 4:4:4 Pixel Format Standard (Fuil Range) set in AMD Adrenaline Software, PC Mode on the TV and can view all the blocks as much as I can on my PC monitor. Maybe it's different because of PC Mode on the TV?

PC Mode will work that way, but it will also raise gamma (which will require a new calibration to fix), lock out most Clarity options (useful for movies), disable ALLM and introduce text fringing. Also sometimes the Black Level auto switch from Full in SDR and Limited in HDR doesn't work, causing black level mismatches after the HDR handshake.

These TVs are pre-calibrated with RGB Limited and just work more consistently good with it.

DLSS continues to improve over time, becoming almost always better than native (at Quality profile) or perceptually equal to native (at Balanced profile), especially at 4K Resolution, which is crazy considering the big performance gains + VRAM usage lowering too.

Sticking to Native res with DLSS available to use has no more sense.

Frame Gen is another story.
It's cool when it works, but it becomes a bit less useful if it still requires 50-60+ fps to work properly (and will also increase VRAM again, along with input lag).

DLSS 3.5 RT Reconstruction seems amazing instead and another setting to always be enabled whenever available if RT is being used.

MMM.. Setting my monitor (LG 27gr95qe) to limited shows me all the blocks but full makes the first 4 blocks indistinguishable. Wonder what I am doing wrong. I have it at Nvidia color settings. 32bit color depth, 10bpc, RGB, and Full. Monitor settings are set at default gamer 1, contrast 70, black stabilizer at 55 instead of 50.

Edit: Turning on HDR makes all blocks appear.

Would anyone know if there's a way to turn on HDR on/off for one display only using the keyboard shortcut? I'm using the Gigabyte M27Q as my main display while my PC is hooked up to a C1 if I want to play on the couch. Doing the Win + Alt + B also turns on the HDR for Gigabyte monitor...

I've never actually been able to see the 12-bit color option on an LG C1 in windows 11. don't you have to use CRU to modify the edid to unlock the bandwidth on the hdmi port? or is that setting just supposed to be available by default?

Use the free O&O ShutUp10++ tool to...

Please do not do this.
Generally speaking, switching off the "recommended" things in the program won't have any adverse effects. The actual performance benefits for doing it are mostly negligible though. It's not something I'd say "don't do this" to but also, you're probably fine without needing to do it.
Disable Core Isolation: from Windows Security settings.

Please do not do this.
This one though, yeah, absolutely fucking not. If you're seriously concerned about completely negligible performance improvements over the security of your computer itself, you're batty. No performance gain is worth taking this risk, especially not when we're talking about potentially less than 1% performance uplift on average. Don't do this.

Also that's not like disabling Windows Defender altogether (which is still recommended to be left on in all cases) but just that extra layer of protection considering how heavy it is on games. Like also said, just using an updated OS, a good Ad-Blocker (and maybe block apps install outside Microsoft Store when everything was already installed/configured on the PC?) and use some brain should be more than enough security for a consumer/gamer PC.

As you say, G-Sync should always be set to full screen mode only.
gsync-ytd4v.png

The "windowed and full screen mode" option is a 'hack' into the DWM to try and make g-sync work in borderless/windowed games, but it never worked correctly.
It would not sync to the correct rate in most games, and would often be enabled on desktop applications which were not games - dropping the refresh rate to single digits until you moved the mouse.
To add, having G-Sync enabled for windowed and full screen mode will also enable it for apps (not games!) that use OpenGL. DirectX or Vulkan render pipeline for their UI. I had it enabled for a while, and it would try to sync my monitors refresh rate to Anki application, which resulted in my screen running permanently at it's lowest capable refresh rate.

Windows 11 has improved HDR support, gets AutoHDR, and the ability to use VRR (G-Sync/FreeSync) in borderless/windowed games rather than having to run them in fullscreen exclusive mode.
I can't stress enough how big a deal that last point is if you use the system as more than a pure gaming machine. Being able to seamlessly alt-tab to something else without having to wait or see the screen flash is really nice.

There are also improvements to scheduling for newer CPUs - which should particularly benefit Ryzen CPUs with more than 8 cores.
And there are further improvements on the way for people using multi-monitor setups with mixed refresh rates.

I've never actually been able to see the 12-bit color option on an LG C1 in windows 11. don't you have to use CRU to modify the edid to unlock the bandwidth on the hdmi port? or is that setting just supposed to be available by default?
The C1 has a 40 Gbps HDMI 2.1 port, so it cannot do full resolution 4K120 (RGB/YCC 4:4:4) with 12-bit color. It is limited to 10-bit.
This has zero impact on image quality, since OLED panels cannot even fully resolve 10-bit yet.
40 Gbps can do 12-bit with reduced resolution - like the PS5 using 12-bit YCC 4:2:2 (half chroma resolution).

Thanks for linking autoactions Koklusz. I don't like leaving HDR on all the time anymore due to fears of burn in, this app works perfectly so far.
The automatic brightness limiter (ABL) is more aggressive in HDR mode, as a preventative measure.
If you keep the SDR brightness setting in Windows to the 0–31 range, you're basically staying within SDR limits (0 = 80 nits, 18 = 152 nits, 31 = 204 nits).
You will be unable to see HDR content outside of games (e.g. web/video content) if the desktop is running in SDR mode.
I'm over 6300 hours with no issues running the desktop in HDR so far.

Would anyone know if there's a way to turn on HDR on/off for one display only using the keyboard shortcut? I'm using the Gigabyte M27Q as my main display while my PC is hooked up to a C1 if I want to play on the couch. Doing the Win + Alt + B also turns on the HDR for Gigabyte monitor...
There is an option in the Game Bar settings to enable HDR for the main display only, but I'm not sure whether this affects the keyboard shortcut.
