I’ve definitely had issues with Linux versions + Wayland; however, most of the time they are easily cleared up by launching the Linux native version in gamescope, which plays nicer with window managers, too.
That said, there really isn’t anything wrong with running things in Proton. Sometimes you can get better performance in Proton with the Windows build versus running the game in Windows (due to various factors, including shader precaching). Compatability layer ≠ emulation, and it’s important to distinguish the two, because “emulation” does and should sound slow. Proton is not emulation, strictly speaking.
As someone still using Steam Controller on the daily, I’m most excited about Steam Controller 2. The original remains the best controller I have ever used.
