This thing ran like an absolute pig for me in VR - 5900x + 3090. Was averaging around 30 fps with everything on lowest settings I could manage. Given the quality of the pancake graphics I am gonna stick to that for the minute which is a bit of a shocker for me because I have not been back to 2d for any other game.
Seriously, have a read through the link I shared above - there's some counterintuitive stuff like setting the EFIS displays to high which reduces stutter giving a smoother performance as well as some great troubleshooting regarding drivers, windows settings etc.
I went from disappointing to really quite playable (even at low FPS it's smooth which is the important point) by starting with his settings and I'm on a 3070 and 3900X so you should be laughing with your setup.
