Easiest approach is to find a distro that has solid and reliable support for Proton, I think. Mesa is another factor to possibly to check on too.

There's a bunch of other details I'm coming across in a couple of reddit threads. It wouldn't be very sensible to try and cover everything mentioned in my own comment.

Worth noting that on a cursory glance at recent opinions, it does indeed seem like AMD typically more widely reliable on Linux than nVidia.
