I use a HP Reverb G2 and have upgraded my GPU last week from 1080ti to 3090. The reverb is a real GPU killer with its 2x 4k resolution + Supersamling and 90 FPS requirement. With the 1080ti AC ran smooth on 150% SS, all graphics settings on low and Post Processing disabled. Now with the 3090 I can use 200% SS, PP enabled, and some settings on medium instead of low, which is really nice.
Unfortunatelly I experienced stuttering in the race last sunday. There were about 15 drivers and in close battles I still had issues. I think the CPU was limiting (it's a ryzen 3900x, actually not slow at all). Will change some settings for the race tonight and hopefully it will work out.
ACC won't work with VR ever I guess (may be with 4090 and very low settings).
F1 2022 also does not work well with my setup, need to lower the settings a lot.
But all in all VR is worth all that trouble, because you really feel like sitting in these cars
