After HOURS and hours of testing and troubleshooting the reason is simple. VRAM Starvation.
For anyone with a 3080 and Reverb G2 crashing upon taking control of the driver in VR :
I never had to lower headset resolution for a game to work but this is the one...
After hitting the menus the VRAM hits 9.6GB usage lowering to 9125 after some idle time.
Try using the Yaris GR WRC1 car, I tried some group B cars and game just froze.
Here are my settings :
nVidia driver 572.83 DLSS Preset J using nVidia Profile Inspector.
Manually put the 310.1 DLSS DLL in the game as the guide tells you to do.
HyperThreading and E-Cores disabled. will retest with E cores enabled later.
Using SteamVR, 90hz refresh, Resolution per eye 36% (yes, that low)
game settings :
game resolution 1280x720 windowed
Basic settings:
AA Low
Aniso off
Main menu famerate limit on
FOV render strength 2
Upscaler DLSS
Upscaler Auto Quality ON
Advanced:
Everything ultra Low or OFF if it allows.
VR Settings Hidden Area Mask Width 108
Height 52
I'm still testing the exact settings but i was able to put two time attack runs in Sardegna, the first one.
Good luck.
