no experience with this game but performance drops happen frequently and randomly for me, Fedora, Lutris, AMD GPU. like, I play a game that I have 100+ hours played on the same hardware and software and everything is dandy - 60 FPS, butter smooth mouse and game play. next day, same game, same settings, no updates in the meantime, absolutely nothing changed - 25 FPS, mouse stutters, horror. next day everything is fine, and so on.
