I did run into a few package version incompatibilities 1 or 2 times, but it was rare to have issues. I think I had more issues on Manjaro tbh.

I was using X in all of those. Now I am on NixOS and Wayland, but haven’t tried steam/big picture yet.

Started on Manjaro but I was annoyed when they let their SSL certificates expire several times so I moved to EndeavourOS. Now I am using NixOS, and I probably stay with it for a while.

I have a RTX3070 and I never felt any lag using big picture/gamepad UI in Ubuntu/Manjaro/Endeavour.

But you can Dual Boot and only use Windows for gaming. I did that initially
