Proton is a better option unless the game needs Anti-Cheat, which most won’t work in a VM, anyway

Personally I dual boot Win10 LTSC with fake credentials and some privacy tweaks for games that need to be on windows

I don’t recommend going that direction. I think you’ll get better results with Proton and Proton-based solutions like Lutris and family.

I’ve tested it, and while it does work, there are some issues:

1. The anti-cheat doesn’t work for all games (delta force demo).
2. Sometimes i had strange sound glitches.
3. I had to use a second mouse. In certain games where you drag the camera (like Sins of a Solar Empire), the camera spins uncontrollably fast.
4. It’s not as fast or responsive, but good enough.
5. Game Pass games don’t run.

Because of these points, I still keep Windows 10 as a dual boot option.

I only play games that work native or via proton. I just use windows for the CAD programs that i need to use. I do gpu pass through and native for my host system idk how this would be for gaming tho.
