I’ve used Arch, Pop_OS for gaming in the past, was looking for a distro that just works and doesn’t have any extra fluff or do anything nonstandard. (For example I don’t like that some programs will only update through the pop shop on pop os and not through the terminal.)
I’ve been using arch with gnome for ages, it doesn’t have anything non standard… Lutris and steam ‘just work’…
OP may want to look at Garuda’s gaming edition. It seems to have a lot of good gaming packages I usually end up installing myself and it’s based in Arch Linux
