Linux

Just make sure the kernel modules are enabled and so are the systemd services. Shouldn't have a problem. It's been butter since they released the VRR fix a few months ago

Games worked for me on Kubuntu, but a lot of other things were seriously broken. Compositor/Desktop effects did not work at all, weird screen artifacts, Taskbar crashes, Discord lags terribly and has display problems. I don't know, if that is going to be the new Desktop experience, we're gonna have a problem.

I've been gaming with a 2080ti in Wayland for about a year now. I can't say I've had any issues related to my graphics card at all. The only hiccups I've had are with a couple of games, maybe two, that I had to tweak to run. They were known issues with public fixes. It's been a great experience.

There was an issue a few months back with multi monitor setups. Anytime I changed a monitor input, it would hard lock. It's fixed now.

I've got an nvidia card and I've personally got no complaints about Wayland! been using it for some time to much success, I feel like x11 is just 'off' in comparison.

Depends on the desktop environment in my experience. On Fedora Gnome it was an unstable mess with my Nvidia RTX card but Fedora KDE Plasma has been stable.

Several months ago I had a similar experience. Even just running plasma with Wayland+Nvidia was enough to cause problems.

It works just fine for me on my RTX 3060 Ti. No significant performance decrease or stuttering at all (except in Cities Skylines II but that's not Wayland's fault)
