Nobara KDE
https://nobaraproject.org/
Made by RedHat dev Glorious Eggroll who has been improving Proton and other tools for Linux gaming. Has a SteamDeck version. Welcome screen installs anything gaming you could want/need.
Tried Debian/Ubuntu distros but needed newer packages/drivers and it was time-consuming.
Tried Arch and derivatives but being that cutting edge had quirks.
Fedora-based Nobara KDE hit that just-right spot of stability vs latest.
Games run better than they ever did on w11.
