Endeavor allows you to pick from a number of DEs/WMs on installationa

I guess you could try an immutable distro (Fedora Silverblue comes to mind) if you want something that just works and you don’t want to use it for programming

That really doesn’t sound right, I have a 930m and it ran GTA V on med-high 720p (on Windows though…), the game itself is ps3/x360 era so you probably have a problem with the driver or maybe double check it’s running on dGPU
