Bazzite comes ready to rock with Steam and Lutris pre-installed, HDR support, BORE CPU scheduler for smooth and responsive gameplay, and numerous community-developed tools for your gaming needs.
I want to add to what the others said. Usually I just add windows programs/games to steam as none steam game. that has been the easiest way to do it for me. I have very few games that isn’t on steam so it is nice to be able to add them together with the rest with the correct categories and such.
