My biggest issue gaming under Wayland is the fact that certain games can’t capture the mouse when run full screen with multiple monitors. I’ve got a number of games that exhibit the issue, but the easiest way to experience it is to try and run CS2 as wayland native (so not under xwayland - As the performance overheads running xwayland are notable running CS2) - Within 10 mins you’ll be looking at the ground with the mouse pointer on your secondary monitor.

Furthermore, running gamescope doesn’t fix the problem - And yes, I’m running the correct commands under gamescope.

I mean - This is basic functionality that should be an integral part of any modern OS. Under X11 running the same dual matched monitors everything works perfectly with great FPS.

Connect the Steam Deck to a compatible dock and you can quite easily use it as a desktop. At the end of the day, it’s still an x64 based PC that’s just handheld.
