I'm 100% sure I'm on X11. CSGO has small but noticeable latency on Wayland on Nvidia so I switched as soon as the install happened.
I did try switching back to Wayland yesterday, and it's plane black screen with the cursor flashing, not even a functioning desktop, let along games. Something must had broke my Wayland some time ago.
I don't know what that is but I had it in launch option and it does nothing as well
