CPU heavy / GPU light graphics settings

Ive got a HP Reverb G2 and have just upgraded my PC, minus the graphics card as it obviously a bit tricky to get the 3080s right now, and i cant quite justify a 3090.

My current system is an i7 10700K (all cores at 5.0 GHz) with an RTX 2080, overclocked as far as i can. The processor is obviously smashing it and averaging about 6-7ms frames while the GPU is definitely limiting it (currently running VR medium with environment detail on ultra and 100% resolution on the headset, and getting around 70fps - if i drop to 80% resolution i can get 90 FPS except in stations)

are there any mainly CPU settings i can crank up without hurting the GPU load much, while i wait for a 3080?
 
Disable shadows, they have the most impact on calculation (and yes, they even overburden a 3090 due to the way they are calculated on 300% resolution [have to go that high with the Vive to get text readable]). also don't use the game's supersampling. Instead, use SteamVR's resolution scaling.

Thanks - im already using the Steam VR resolution scaling. Im more wondering if there is anything i can turn up, since im OK with my current FPS. Turning shadows down might let me turn some other stuff up, though.

Edit: i think if i put the G2 at 300% resolution my PC would explode. 100% is super clear though.
 
This game isn't very CPU limited and there aren't really any meaningful CPU dependent settings that can be changed.
 
The best thing you can do is turn on motion vector reprojection and not compromise anything.

\Steam\steamapps\common\MixedRealityVRDriver\resources\settings\default.vrsettings

Code:
// Motion reprojection doubles framerate through motion vector extrapolation
// motionvector = force application to always run at half framerate with motion vector reprojection
// auto = automatically use motion reprojection when the application can not maintain native framerate
// disabled = turn off motion reprojection
//
// Comment out or remove this line to use the SteamVR settings for controlling motion reprojection
"motionReprojectionMode" : "disabled",

Change that to :

Code:
// Motion reprojection doubles framerate through motion vector extrapolation
// motionvector = force application to always run at half framerate with motion vector reprojection
// auto = automatically use motion reprojection when the application can not maintain native framerate
// disabled = turn off motion reprojection
//
// Comment out or remove this line to use the SteamVR settings for controlling motion reprojection
"motionReprojectionMode" : "auto",
 
Use VR low profile, but turn blur off and set textures/material quality to high/ultra. See what kind of performance you get and use it as baseline.
