There are distributions with a great Steam experience out of the box? It’s SteamOS actually a good choice? Maybe isn’t what you use or prefer.
A good Steam distro for me has a very mininal procedure for perfectly working controllers, client and general user experience.
Your direct test and experience are very appreciated.
Copying from the old thread:
Nobara Linux. The official website is WIP but it’s essentially a distro aimed for gaming, with the important things like Steam and Lutris pre-installed.
I’m currently using it and it’s pretty good and reliable. It defaults to wayland though, you may want to go back to Xorg if you’re using an Nvidia gpu.
