On proton experimental the oceans are red and some selection boxes didnt blend well
When in the tutorial screen, there seems to be a edge limit so you cant select the last view pages and exit, had to force quit.
Screen was set to 1080x1920 so maybe the cause? didnt test lower resolution.
Game doesnt like steam overlay after proton 5.13-6, causes the game to crash on the main menu after 2 seconds, fine if you disable overlay.
Takes a solid 2--3 minutes to launch, even on SSD (Works like a charm though, just be patient :p)
Tried throwing everything at it, nothing worked. Tried from oldest to newest proton. Tried Protontricks. This game just wasn't launching.
OK if you don't mind the graphical glitches everywhere
The game crashes when the resolution is set to 1920x1080 - whatever the quality settings are set to - but works with 1600x900, even in "High quality".
Once in-game though, several textures are missing and the rendering of some areas is buggy (ground, water mainly). It's particularly visible when the quality is set to Low.
Otherwise it seems to be playable and the rest seems to be working as expected.
Runs out of the box on proton stable 3.16-4
No problems at all.
