Don't see it mentioned here - Nobara. Fedora tweaked by Glorious Eggroll to be as compatible as possible with games ootb. Worth looking at.
I used to use Arch but Nobara works too well for me to go back.
A big thing for me too is the custom version of OBS that the welcome GUI installs is excellent and allows for application specific/exclusionary audio sinks so I can screen record games without having audio from discord/music.

Idk how to do it through the settings UI, I just navigated to (nsfw warning) https://kbin.social/d/lemmynsfw.com (nsfw warning) and pressed the block symbol next to subscribe

fwiw i blocked the lemmynsfw.com domain from view and I haven't seen a single instance of nsfw since
