Switching to proton 6.3-8 was necessary as newer versions caused errors in showing animated 2d graphics on the menu, opening cutscene, and videos in-game rendering them completely unviewable, with grey lines, zoomed in, and the rgb values offset from each other. 6.3-8 was the latest version which showed these elements fine, and the game otherwise ran fine at 60 fps. The keyboard layout worked fine except several buttons including document reading and map controls were not mapped by default, so I had to change 3 or 4 buttons to match these keys in the game. There may have been an issue with the in game voice chat but I wasn't able to test it at the time.
