My experience with Nvidia+ Wayland was… Less than desirable. Enough to make me pickup an AMD card.
However, once I did that my experience instantly better. Hell, even X11 worked better - I was never able to get the desktop to stay at a consistent 60FPS (I’m still on a 60Hz panel which I’m just now getting around to upgrading shortly) in X until I moved to my AMD card.
The 545 driver update just made things so much worse. So I’d say Wayland+Nvidia is not great (for others it works fine so maybe it’s down to what card you have?) however on my AMD card (and my old MacBook with Intel integrated graphics) it’s fantastic.
Xorg has no fractonal scaling so I have been uaing wayland since I have switched to linux on nvidia and yes I use it for gaming. Not silky smooth but great so far.
I really don’t like nate’s take here. IMO it’s really not that good, Wayland is still outright lacking features, even when using the craptastic xdg portals junk
