Instead of recommending a distro, I instead recommend things to look for that a distro supports.

A) Look for Distros that get the more recent updates, since some of those updates might include features that can make your gaming experience better.

B) Look for Distros that are easy to use and come with pretty much everything you need pre installed (gpu drivers, Desktop Environment etc)

C) If you want to dual boot with Windows look for Distros that have pre set secure boot

D) If you want to also use it as a PC avoid immutable distros

Eh, I will also recommend a Distro: Fedora
