I’m using a 3080 and I do seem to have the occasional problem that my ATI using friends don’t, nothing that has prevented me from playing.

Example: Recently, gamescope hasn’t been working. So I’ve been using xwayland instead. Basically I don’t get HDR or VRR, but it’ll be fixed (it may already be fixed because I’m on a rolling release distro (Arch, btw)).

I haven’t, yet, run into a ‘This game doesn’t work because you have an NVIDIA card’. On the other hand, I can run local AI trivially easy because my card supports CUDA.
