Linux for sure, I love gaming on Linux so it’s a priority, and as a platform I can test it makes sense. I have both an older Linux Laptop running Fedora + KDE + i7-4700, as well as a Steam Deck(No Steam Machine RIP but should work) so I will be testing those and getting those working for sure.
Mac is a bit trickier since I can’t test Mac since I don’t have a MacOS machine. I can build for it but we can’t officially “support” it because I can’t do any testing at all.
