The native version has some black textures that will sometimes flicker rapidly (epilepsy warning). Forcing the use of proton fixed this problem and the game renders properly. I believe the only crash I had was on startup from launching the game from the launcher for the first time. But besides that the game ran great on proton. I did have a problem changing my refresh rate in game. For some reason, the game would not let me change the refresh rate to anything higher than 60hz. I'm guessing that this is a problem with proton, since this is also a problem with other titles.
