I just checked out their forum and I can only wonder why. There seem to be multiple cries for help from devs with no comments.

Making games is already difficult, nobody wants to do extra mile to support a platform, Valve made the right choice with proton, unfortunately, that means less incentives to have a native gaming experience on Linux.. I'd say the tradeoff is worth it

Apple should do something similar, but they'll never do since their users expect quality over anything else, wich is why they market Game Porting Toolkit as a testing platform, as opposed to a shipping platform for Valve's Proton, even thought it's basically the same project, 2 different culture, Valve doesn't care if the experience is worse

I just meant, that if the process to get help isn't helpful. A lot of new comers won't try.
