Y'all have no idea how true this is. I just finished building my OC and installed CachyOS (Arch derivative). Got Steam running incredibly easily. I can play both Deep Rock Galactic and Helldivers 2 online multiplayer. The only tweak I needed to do was use a different version of Proton for Helldivers 2 (which would've been the default one, but Cachy has its own Cachy one).
I don't know when the last time y'all have tried to play games on Linux is, but it is genuinely trivial. Even Nvidia drivers are easy now.
I just installed mint on a little gaming PC connected to my TV. Set it up to boot straight to steam with big screen mode. The only thing that is a small chore was installing xpadneo for my controller and downloading many many gigs of games into it.
VRR is Variable Refresh Rate. Its a nice feature that let's GPUs talk to compatible monitors so that you dont get duplicate, wasted, or torn frames. The monitor adjusts its frame rate to the GPU and the GPU doesn't render more than the monitor can handle.
