Hi everyone, I just finished writing a guide on everything you need to know in order to game on Linux. It covers Proton (Steam play), using Heroic Launcher (with Wine-GE), and all sorts of tidbits and tips I wish people had told me earlier. I hope this can be useful to someone out there!

I’m pretty sure WinBTRFS’s readme has a section about properly setting up the user and group permission stuff. Essentially just providing the Windows UUID to Linux POSIX equivilant, which generally ends up fixing all the permission related problems. The only real caveat is it not working with SuperFetch, so files aren’t cached in memory and have to be loaded from disk with every read.
