I know nothing about Gamepass, but Mint runs Steam games on my 2080 just fine. It worked out of the box. I was a little surprised. To keep Steam from forcing me to update FO4, I bought it off GOG and installed it through heroic, with zero issues. It just worked.
But, no, it’s not easy-peasy to switch, you do need to be motivated to make the effort. Of course, there is a learning curve. Feel free to stay on Windows, that was always allowed.
