I’ve dabbled with Lutris and Heroic. But Lutris only showed me the Windows patches during its update (which obviously don’t work).

Heroic on the other hand doesn’t work as well as I’d hoped. All operations take a really long time and some of my GOG games don’t show at all (in Lutris they’re appearing). I’m using the current version 2.13.0.

And even if it works, I’d be interested how Heroic implements its update mechanism for Linux native games since it should have the same issue regarding available data :)

I considered just installing the new .sh file in the same location, but wasn’t sure whether that breaks my saves in the worst case. So it’s reassuring to hear that others had success with this method. I’ll try it when I get an update for one of my Linux native games. Thank you :)
