i have the opportunity to potentially jump into pc gaming by picking up a friends old PC, specifically for VR, specifically for sim racers like dirt rally and pcars 2, and wanted to get some feedback re' 1) the builds likely performance capabilities and 2) a fair price. i know next to nothing about pc gaming and pc vr gaming.
i7 2600k overclocked to 4.4 ghz
1070 gtx
16 gigs ram
500 gb ssd
1 tb hdd
An Overclocked 2600k is perfectly capable of delivering a VR experience. That's what I used for my setup for a while. Of course a 2600k OC's is basically the bare minimum and getting a recent CPU will give you a much more stable/smoother experience so I'd suggest they save for recent parts.
FYI, the system that sold me on VR (via pcars2) was running a 970. not sure on the cpu, but it was slower. i know we put the settings at basically the lowest, probably lowered the field of cars significantly (and even hot lapped solo), and it still was a bit questionable frame rate wise. and i still sat for a straight hour doing lap after lap on laguna seca!
For Dirt Rally and Project Cars 2 specifically?
I wouldn't recommned that system.
I recently installed FCAT VR and did some benchmarking with the Project Cars 2 demo and Dirt Rally VR, to judge how my system would handle a Valve Index at 120hz/144hz. Both with the HTC Wireless adapter and the 5m cable.
4770k @4.2GHz, 2000Mhz DDR3, 1080 Ti SC2 +70/+340 Max P/T target.
I can share all my FCAT data with you if you want me to.
DR, 1913x2135 - 3.5 minute race, snow daytime, Custom settings
Cable: 180ps unconstrained, ~90 delivered and 16 dropped frames, sub 5.5ms avg frametimes overall. Good experience, but my rig is old.
WA: 137fps, ~88 delivered, between 90 and 500 dropped frames, 7.5ms avg frame time, lots of stuttering. Bearable.
PC2, 2138x2376 - 10 minute race, rain conditions, replay system, 1x in game SS, Custom settings
Cable: 70 fps delivered, 93 unconstrained, 10,000+ dropped frames, 10.66 avg frame time. Really Bad.
WA:: 48fps delivered, 77 unconstrained, 20, 000 dropped frames, 12.8ms avg frame time. Even worse.
That system is worse than mine. While I am supersampling, that's mostly a GPU related bottleneck. Based on the CPU/RAM alone - Build a new computer, I implore you. Project Cars 2 doesn't mess around at all.
Here are the
Rift and
Vive system requirements. For a WA, a 4+GHz 6 core system (Vive) or an 4-5GHz 8+ core (Vive Pro) is needed.
