The regressions are what bum me out about playing Windows games on Linux.
Games like Yakuza 5, where Proton worked for awhile, but then broke. So you need to manually use year-old versions for the game to run correctly.
EDIT: Funny I should mention Yakuza 5, because I just tried it on this new version, and it works again. (No wrong audio on cutscenes. No getting stuck on the initial load screen when starting the game.)
