Sometimes when I launch a VR game I get 10-12 fps exactly. it sometimes goes away when I switch between 144Hz and 120Hz mode couple of times. If I adjust resolution per eye it's solid 144fps on 68% and 10-12 on 70%, also 10-12 on 500%. It sometimes gets fixed if I restart steamVR. When the problem doesn't occur I can usually run things at 200-300% resolution comfortably. I'm on 2080Super and use Index.

I think I'm going a bit crazy, after googling still haven't found anyone with similar issue. It's driving me crazy.
