xwayland on desktop, they are migrating to Wayland, they use kwin but you can use gamescope of you want. In gamemode it’s fully Wayland, uses gamescope.
Same with 32 bit, they are working towards a 64 bit executable.
Now that Valve is balls deep into Linux, we’ll all see major gains.

I think in the current stable it uses Wayland in desktop mode and a modified Wayland called Gamescope in game mode.
