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 don't know much about these linux gaming distros but I have heard some good stuff about Bazzite. There was also Nobara which has the same idea but non atomic. It also has Lutris and Steam pre-installed and some kernel modifications but no idea how it is doing :3c
Having personally used both before and I can say that both are quite good. If you don't tinker much or you run a Steam deck, go with Bazzite. But if you like to mess around a bit more, try Nobara
