Lots of gamers like Nobara—it's an independently released modified version of Fedora with a bunch of user-friendly fixes and tweaks. They don't just preinstall stuff; they actually patch and modify things to make gaming performance better. They have five different versions: Official KDE, clean GNOME, clean KDE, and two Steam Deck-like options for HTPC and handheld devices.

Admittedly, I haven't yet tested it out, but people seem to love it. I am not a big desktop gamer, so I prefer the thoroughly tested Fedora Edition releases for my daily driver. Fedora only supports and includes free and open-source software, so 3rd-party proprietary packages are always absent from a fresh install, but they are easily enabled.
