I’ve tried running Plasma 5 on Wayland occasionally but due to having NVIDIA card there’s always been bigger or smaller annoying issues so I always reverted back to X11.
Looking forward to try out Plasma 6 as soon as it’s released!
i have a rtx3080ti and am using KDE plasma 5 wayland on Fedora 38(now 39) exclusively for gaming. i made the switch to wayland a month or so ago and i am having a considerably smoother experience than x11. especially with multiple monitors and flatpack apps like discord in the mix.(steam is running native though). no issues that i am aware of so far
