It works via dolphin. (I just copy game folder from PC - Win11, to HDD, then connect HDD to LLGO and move to Bazzite (steamapps/common), then click to install (moved game) in steam it just verify game files, download some updates and start.
With this, I still can't get my single monitor to go 1440p 144, but 1440p 120 is possible. I'll try under X and see if it is any different, but I do really enjoy wayland lol
