I just use Fedora 43

Bazzite may be helpful for those coming from other platforms, but I just use F43 for gaming. I have Steam, Heroic and Lutris installed. I mostly use Steam but Heroic is good for some non-Steam games. Lutris is a mess in my experience. The lack of documentation and the peculiar (to me) interface put it way down the list. I strongly recommend visiting protondb.com for real-world feedback on how games actually run and what tweaks may be required. And install GE-proton, which is often more up to date than the stock Steam library.

Slightly OT: much kudos to the people behind the Sunshine streaming server and Moonlight client that let me play on my TV from the sofa.
