… and it’s much, much better than I anticipated. Proton has solved so many things. I’ve been dual booting on a smaller partition so far, but this has convinced me to wipe the whole disk and use it for Linux only. I might still keep a dual boot in case there is some edge case, but nothing so far has been an issue. I’ve been running Pop_Os! which I also have on my laptop since some year back. Previously I’ve also always had Arch on my laptop, but always stuck with Windows for my desktop just because of gaming issues.
It is highly recommended that you use Lutris, Heroic Launcher or Bottles to prepare an environment for the SW you are trying to run. This offers the most flexibility.
To use the official Steam Proton, you need to add an “external game” which will be the SW you want to run.
