It’s surprising to me it’s not higher. Gaming is excellent on Linux and Windows 11 is simply not good. Just a relative easier distro like Ubuntu is outstanding and learning curve is lower than ever.

I think it's going to keep increasing. I know people who resisted linux for decades and after playing with a Steam Deck are now considering building a linux gaming PC. This is in large part because they are investing into the Steam ecosystem for the first time ever and seeing how great it is. Mad props to Valve for all their work on Proton and Steam.
