Installing the additional Windows Components using Protontricks fixes "ERROR: Couldn't initialize DirectShow". Game runs fine after that.
Install Windows Media Player 11 and DirectShow.
When you Alt-tab out of the game, It hangs for several seconds when returning to the game and the game will stretch to the default resolution of your monitor if you were using a different resolution.

I tried multiple versions of Proton including Proton GE but got the same results, a crash from WINE which led to nowhere.

If you want to play this game then your best off using Microsoft Windows where I am sure it continues to run flawlessly

Able to load into the menu with stock proton but doesn't load into the game and gives a codec error. Loads into the game and runs fine if you use GE proton. I did use a keyboard and mouse while playing and an external monitor.

Use proton experimental (as of 06/08/2021) to get around codec error on start. Menu background will be bugged, but the game works normally.
Use proton experimental

Use proton experimental (as of 2021/08/05), should get past no codecs error. Menu background is bugged but game is fully playable.


Crashes just after the splash screens with "ERROR: Couldn't initialize DirectShow. Perhaps the necessary Codec for the video format is missing?"
