The point of VRR is smoothness and low-latency. The removal of tearing is ancillary, and not a guarantee unless it is combined with v-sync.
I won't go into all the details here, but G-Sync originally
required the use of V-Sync. When you enabled G-Sync, you
couldn't disable V-Sync. So don't think that G-Sync replaces the need for V-Sync.
It's difficult to say, without details about your monitor.
If it's anything more than a 60Hz display, you shouldn't have to worry about latency if the game is being limited to 60 FPS.
The optimal setup for a VRR display in
Deathloop is to:
- Disable in-game v-sync.
- Set the in-game frame rate limiter to 60 FPS (turning off v-sync is what enables the limiter).
- If you get screen tearing because your monitor's maximum refresh rate is not much higher than 60Hz, enable v-sync for the game via the NVIDIA Control Panel. This may mean longer load times, but guarantees no tearing.
Having V-Sync enabled with G-Sync will not add latency when the frame rate is below the maximum refresh rate of the display.
If it's working for you, stick with it I suppose, but these settings don't seem optimal.
- If it's a 120Hz VRR (G-Sync) display, I recommend using the settings posted above.
- If it's a fixed-refresh 120Hz display, enabling half-refresh v-sync in the game should be enough for smooth performance. It treats the display like 60Hz, without the hassle of actually switching it to 60Hz.
Combining multiple frame rate limiters - epecially 60 FPS limiters
at 60Hz - seems like a recipe for introducing stuttering.
