Rfactor2 The VR thread -settings & tips

anybody have any clue why this gray washed out band progressively appears at the bottom of image (quest 2 + steamvr)
 
FYI: The gray bar issue with the quest 2 is a result of v.25 of the PC software. Rolling back to v.23 fixes the problem.

I remember having performance problems ie not running more than 45fps with FX 8350 in many VR games including Rfactor 2, so i upgraded to Ryzen 7 3800x but i could only run 5-10 cars at 90fps, now with Ryzen 9 5950x i can run 20-35 cars without any problems with the same RTX 2070 Super at 90fps.

But since i dont own any intel CPU's i have no idea about the performance on them (due them being too expensive to be bought and tested)
But atleast it seems the performance seems to improve between all thease 3 cpus quite drastically.

For comparison

Intel Core i7 3770k @4.5GHZ Sebring alone on track 240fps
intel Core i5 9600k @4.8GHZ same conditions 380 fps
Amd 5900x @ stock clock same conditions 440fps

Somehow the new AMD cpus are really fast in rFactor2 ,at least the 12 core verion, maybe caused by the big level 3 cache. rFactor2 is bandwith depending and it could help to reduce data comunication between CPU, GPU and Ram
 
Nvidia Drivers 461.72 with Release Candidate I'm finding that after a lap or so of Spa I start seeing rapid fluctuations in fps, dropping to 72 and back up to 90 causing a jittering experience. The GPU usage remain between 62-70%. Anyone else experiencing anything like this?
 
What's the best way of recording VR?

I've been trying out OBS and using Oculus Mirror, but I don't like the performance hit. Setting rFactor to mirror mode is a bit better, except the field of view is too narrow.

Just quoting myself BUT if anybody experiences this issue above I seemed to have resolved it. Not sure which of these fixed it or if it was due to a combination of them:
  1. Deleted the contents of the CBash & Shaders folders
  2. Deleted the contents of the Cache folder in player/LocalStorage
  3. Disbaled Motion Smoothing in SteamVR (I personally think this may have been the culprit)
No longer getting the constant stutters after a lap or 2 of racing. Tested this weeknd on Spa and did about 8 continuous laps without a single jitter, so I think safe to say my issue is resolved.
 
I have been having some issues with Rf2 of late (see above post where I thought I had fixed it).

What I am finding is that on racing I start getting spikes in GPU frame time and these get to the point where they become so consistent that the game becomes a stuttery mess. GPU usage doesn't go beyond 65% and CPU usage around 45% (GPU temp max 70c & CPU 60c). Things I have tried:
  • Reinstall rF2 & all mods form scratch
  • Lowering graphics details down (GPU usage around 50%)
  • Changing XMP profile on Overclock
  • Various Nvidia drivers (currently on latest 465.89)
  • VR Pre-rendered frames 4 on NCP
  • RC version and stable version of rF2 (typing this I realised I have not tries the old UI, so may need to try that to rule the new UI out)
  • Adjusting FFB core true/false
  • Uninstalling/installing: SteamVR, WMRfSVR, & WMR software
  • Removing Fanaleds plugin & software
  • Running the game without Simcommander software running
  • Updating latest Fanatec drivers
  • Uninstalled all RGB software for mobo
  • W10 updated and all mobo software/BIOS up to latest versions
I feel like I have pretty much tried so many things just short of reinstalling W10 and have been entertaining the idea of memory or PSU issues. I should point out that rF2 is the ONLY game I am experiencing this BUT I wonder if it was a hardware issue, would it not effect other games? I ran MEMTEST a month or so ago with no issues.

So the game runs well on a monitor but the GPU frametime spikes occur only in VR. The things I have noticed:
  • The frametime spikes occur usually after 1-2 laps of the race starting - possible memory leak caused by drivers/software?
  • not replicating the HMD on the monitor decreases its prevalence
  • If I press Win+Y they are less prevalent but do occur in some instances (see below)
  • Even with Win+Y if I spin or crash the car, they will start and persist even when no cars around on re-joining the race
  • They have no relation to graphic settings
My test bed is using the Mclaren 720 GT3 at Spa with 21xGT3-AI (all S397 official content), random grid position and starting a race with race time at default.

It's driving me insane finding what the issue is. It's a relatively new issue that I have noticed since rF2 moved to RC but I can't be certain if it was one of those updates, and if it was, surely I would not be the only person experiencing this.

So my feeling is either a driver, plugin or hardware issue is causing the spikes. Now before I look into re-installing W10 &/or investing in a PSU/RAM, I wonder if anybody here has experienced or is experiencing anything like this? I'm using a HP Reverb G1 with Steam VR set at 100% with no reprojection enabled.

EDIT: tested with old UI but issue still persists

Do you have all those cars visible in game? If so, try knocking it down to 10
Thats the thing that caused all my problems.
 
I have 14 visible. I can also confirm it is occurring on the old UI.
@Manfredk2
I tried various drivers but I believe the issue has now been resolved by Nvidia.

no it isn´t. Issue is definitively not fixed by Nvidia. Do you use FPSVR? Are there purple spikes in gpu frametime?
Click to expand...

Yes I started using fpsvr to see what was going on but not all the time & the GPU frame time spikes purple.

I do have MSI afterburner too to control fan and GPU OC.

I did come across that article when researching the issue but thought it had been resolved so it is still definitely a thing?
 
MSI afterburner could be a trigger for the issue. Maybe try without running it.

Nvidia released a driver fix some time ago. This helped a bit but didnt resolve the issue completly. The promised final fix is still not in sight...

Befored the fix i had a lot of purple spikes when running for example S397 GT3 at Spa. After the fix the spikes were gone at Spa. But the spikes are still present at other tracks although my frametimes are as low as yours. For example: i have rocksolid 90 fps at Watkins Glen at start (10 visible GT3 AIs, starting from last place. After two or threee laps single spikes are coming. Then often 10 or more purple spikes are coming within a few seconds, causing a massive stuttering, although there is only one visible car before me. Its not replicable why this happens...
