Symptoms

Proton 4.11-10:

• The default resolution required is 1024x768 but this version of Proton only lists my system resolution (1920x1080). This leads to several errors and the game doesn't load.

Proton 4.2-9:

• The game loads and renders properly but tend to crash rather often while playing a game or even during the tutorial.

Reproduction

1. protontricks 73170 -q --force dotnet20sp2 gdiplus directplay winxp
2. Launch the game, launcher will show up, uncheck play intro and then click launch.
3. Click tutorial and select any tutorial.
4. Crash and burn.

Start by reproducing the reported behavior using the listed protontricks command and launch steps with Proton 4.11-10 and 4.2-9. Inspect the attached steam-73170.log files while checking the resolution failure and tutorial crash; done means the game launches at its required resolution and the tutorial no longer crashes.
