Gaming on steam works on Centos/RHEL as well as Ubuntu too. While most folks would not think of Centos as a desktop OS, we end up using it for our dev workstations as it matches up nicely with production servers. Christmas time last year, ended up having a bunch of vacation time to burn through and set out on a quest to get a game running on my work rig.

The planets aligned with Centos 8, Steam, and AMD drivers somewhere around late January. Things went from crazy difficult to just working.

Over the Spring/Summer/Fall I've seen significant progress on what worked on Windows vs Proton vs native Linux. A significant chunk of my Steam library now plays on my primary box. When the day comes where I actually get my hands on a new CPU/video card... those will actually go into my workstation.
