If you're only testing on one set of hardware, it isn't going to tell the whole story. The results might be very different on an AMD vs Nvidia GPU, or even on a brand-new vs 1-3 generation old GPU.
Probably the most important thing for gaming is driver support and ease of installation. This sometimes runs directly counter to other general-purpose needs.
I'm still on the hunt for a distro where everything I need is easy to install. I don't think any exist, primarily because GPU drivers suuuuuuuck, especially when you need CUDA or ROCm to work.
Thanks for the recommendation! I was looking at the Fedora family since AMD officially supports RHEL 9. Hadn't gotten as far as to figure out how well that transfers to Fedora and its derivatives. Good to hear that it works.
