I think mint has timeshift enabled by default. Try going back to when the games worked and figure out what change caused the gamss to break?

Oh okay. Thanks for the simple explanation :)

Can someone eli5 pls?

I use i3 which exists only for Xorg.

I’m using proton + Arch for over a year and I have no issues running any games (Ryzen 5 5600X, RTX 3060 Ti). Only issues I had were with anti cheat.

Okay. Also how beneficial would this be for my résumé if I’m trying to get into cyber security field?

I’m interested. Can you tell me more about it?
