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.
