Have you tried Proton on Linux? Checkout https://www.protondb.com/ for games compatibility. The coverage is pretty darn good, e.g. Cyberpunk runs pretty smoothly. Where you'll hit a hurdle is anti cheats, but that's spyware anyway, people should stay away from them.

don't care for anticheat, main concern is VR library
Ah, haven't tried with VR. Just try it, I guess it will depend on driver support. I generally don't touch proprietary drivers (so no NVidia), but for VR NVidia could be better.
If I may add, dual booting, or live USB to switch to Linux rarely leads to success. If you are serious about switching, you need to commit to it. I used to dual boot for a long time, but I never really committed, around about 15 yrs ago I just went "wth, let's go for it, I'll learn stuff", and never looked back.
I would also say don't try lots of distros trying to find the perfect one. Just pick a mainstream distro, and go with it. I hear Mint or Pop_OS are good for starters. If you are a bit techy, you could try Fedora (that's what I use).
Good luck 🤞🏾
