I found the distro really doesn't matter much anymore for gaming specifically. You'll install the same or similar tools for gaming no matter if using Arch, Fedora, Ubuntu, Debian etc.
For gaming it sometimes can be useful to have more current Software especially if playing new games since issues might only be fixed on the latest version.
But aside from that one part I think you should go with the distro you generally prefer and game on that.
Nobara is a great gaming focused distro, it's a fork of Fedora by a well-known Red Hat employee.
It's by the GloriousEggroll guys, and I really liked it a lot. I would still be using it if it worked better with my laptop's hybrid Nvidia graphics setup. When I get around to swapping my desktop to linux, I'll almost certainly go with Nobara first.
FWIW, Pop!_OS is where I landed for great hybrid graphics support.
@shreddy_scientist @alehc Well, not just for gaming, but for beginners, or people who like the simplicity of the desktop environment, Linux Mint. I used it for quite a long time, and altough is has some quirks (as any linux distros do), it is a decent all-rounder, for everyday use and for gaming too.
That's what makes Nobara so rad, it works great for gaming because it has a number of the most downloaded packages built in!
