Symptoms

The game will not launch out of the box, but this was a problem with the game itself. An issue with graphic drivers will cause buffer overrun. This is a launch option that fixes this issue. But from there, the problems COD 1 has are nearly identical to playing the game on modern Windows versions. You have to add these launch options:

__GL_ExtensionStringVersion=17700 %command% +set r_mode -1 +set r_customheight 1080 +set r_customwidth 1920 +set cg_fov 80 +set cg_drawfps 0

After adding these options, game seems fine, though videos will be black, but this is the same thing as on windows.

The only other problem I noticed was that even after this, there seemed to be a slight mouse acceleration issue. Like I was moving the mouse to fast for the game. It's hard to describe, but I don't remember it doing this on Windows (which I dont have dual booted anymore).

I should also note it's expansion United Offensive has basically identical issues. (I will make a separate page for it shortly).

I don't know how Proton intends to handle games that require 'fixes' even on Windows.

Reproduction

Install game, launch. Add launch options given.

No source file, test, or entry point is identified. Start by reproducing Call of Duty (Steam AppID 2620) with Proton 4.2.2 using the reported launch options, then compare behavior with and without them; done would require a clearly scoped, reproducible compatibility fix rather than only documenting workarounds.
