I can say quite happily that Yakuza Kiwami seems to be passing the Linux test so far, well… kinda. Other than not being able to close the game properly, and having to spam the save button in order for it to generate a save for some reason, it’s pretty much the same performance that I get under Windows, framerate is pretty much the same and I haven’t run across any graphical glitches. I even got a few achievements! They were all centered around Majima but… meh.
Perhaps a few Proton versions from now it’ll work like a native game! One can hope anyway.
