I must admit, I found that to be exceptionally true for ARK. Missing textures, absurd bugs... They clearly all but abandoned their Linux version. Ran it with Proton, and things looked nice again, and it ran better in most cases.
That said, I've found Drox Operative runs great on Linux. None of the neglect I've experienced with other games. The only real issue I have is the way it starts up on my left monitor every time I start it. I think this happened with a triple monitor config, and it has happened every time on a dual monitor config. Easy fix though. Quickly shift+super+right arrow, and it's on the center/right monitor.
