Symptoms

The game crashes on launch regardless of the proton version. The logs indicate that SM4 instructions in d3d are not implemented but required by the game.

Reproduction

1. Install the game
2. Run the game
3. After a sound effect the game crashes. Probably in the first frame the game tries to render.
