Hello @gother666, skimming through your Proton log, these look like some lines of interest:
err:d3dcompiler:D3DCompile2 Failed to compile shader, vkd3d result -4.
err:d3dcompiler:D3DCompile2 Shader log:
err:d3dcompiler:D3DCompile2 Resource/Engine/win/Shaders/SpeedTree8Shaders/3d_trees_ps.fx:214:1: E5000: syntax error, unexpected KW_DOUBLE
There's a bunch of other shaders with the same syntax error.
Nothing extracted yet.

Symptoms
When you start a new playthrough by hitting the 'Tee off' button, the map loads but the graphics stop rendering. Some textures like a few numbers and borders are shown but most of the screen is just black.
Reproduction
Install the game and start a play. No matter which map or game mode you select, the issue remains the same.
