Works perfectly and just like native, so just use native instead.
It has a great native linux port, no need to use proton at all... although you definitely can if you face any issues with native.
No issues found
Works flawlessly out of the box.
Works great right out of the box.
Works nicely on deck!
A bit of stutter when you open the game or deploy in a new map, but it goes away.
Works with Proton 7.0-1
Not sure if they updated the game. On default the game doesn't show anymore using any Proton version. However it launches and plays fine when forcing Proton 7.0-1.
Borked - Wont load
Steam Play doesn't work, as of Nov 2021
Tried with Proton Experimental and Proton 6.3-7
Had to install dotnet40, xna40, vcrun2017 and dotnet45 in the game’s prefix with " WINEPREFIX=/home/[username]/[pathtosteamlibrary]/steamapps/compatdata/975510/pfx/ winetricks" winetricks alone doesn't do anything and you'll need to force with -f dotnet45, however it needs wine 6+ the one installed in ubuntu doesn't work install winehq from the page, install dotnet40 and xna40 first
The menu sometimes slows down when you get out of a game session
Doesn't launch. Tried to do the things the other users suggested, but I couldn't figure it out.
Had to install dotnet40, xna40 and dotnet45 in the game's prefix as suggested by @Notmingbag. With those components installed, game worked flawlessly.
WINEPREFIX="/home/[YOUR_USERNAME]/.steam/steam/steamapps/compatdata/975510/pfx/" winetricks xna40 dotnet40 dotnet45 use --force on dotnet40 and dotnet45 or else it doesnt let you install them.
Doesn't start
No luck. Did not start all.
Tried various proton versions and GE.
