I can run 99% on Linux + AMD + X11, on Ubuntu 24. The only problematic one is Witcher 3 which insists on Wayland which breaks everything else. Even the UT5 titles work well enough, but then again our gaming is not your gaming and you might be more demanding that we are.

I'm trying to recall how NVidia behaved for games, but my daily driver is an old 1050 Ti that's been rock solid for years now, also X11.

Maybe the problem is Wayland not NVidia?
