There’s a lot of back and forth on this question constantly in the community. IMO you should just choose a Linux distro that’s beginner friendly with sane defaults. Any of them can game, basically.
Nobara Linux is made specifically for gaming, you might want to start here.
ZorinOS is made for people who aren’t used to Linux. It’s got a great UI and good features. I used to play Elden Ring on it, it’s very reliable.
Pop_OS is another great general distro. Lots of people gaming use this. They’re also making their own desktop environment which they’ll use here when it’s ready.
Arch Linux only if you know what you’re doing. If you don’t, avoid an arch linux based distro.
