I've been debating making the switch for a long time, but after spending like a week researching Proton, Lutris etc. on Linux, I decided to try it out and nuked my entire Windows 11 drive. :)
So far, every game I threw at it works perfectly fine, including Elden Ring & Cyberpunk.
I had to spend a little time troubleshooting some small issues but it's part of the fun!
Specs are in the neofetch, my compositor / WM is Wayfire (Wayland) :)
Yeah, I would even say that most custom kernels have a very negligible advantage in gaming. I know the zen kernel aims to reduce latency but I would say it comes more down to compatibility and features. For example one rather recent thing I remember since Fedora changed this as well is that the vm.max_map_count is already set on linux-zen to the same value the SteamOS kernel uses (I think it's just INT_MAX) that helps with game compatibility on Wine/Proton.
