I dunno, just felt better not enabling a whole repo just for one app, so I went with the flatpak version.
Super easy, just install it and go. Just remember to also install the Proton flatpak package in order to enable running Windows games on Linux. And to enable it in the Steam settings. I don’t think there’s much else to it other than standard flatpak stuff, like things don’t work too great if the system GPU driver version is out of sync with the flatpak one. So if you upgrade one make sure to upgrade the other, etc.
Give it a whirl if you like, and if you bump into issues I might be able to help. We’ll see. 😅
