after the starting text the screen stayed black and music played what's wrong?
This sound like the same or a similar problem like I got: After the developer logo I heard ambient noises, but the screen just stayed black. In the Player.log file I could see the following lines:
WARNING: Shader Unsupported: 'Hidden/Nature/Terrain/Utilities' - All passes removedJust starting the game with the parameter
ERROR: Shader Shader is not supported on this GPU (none of subshaders/fallbacks are suitable)WARNING: Shader Unsupported: 'Hidden/Nature/Terrain/Utilities' - Setting to default shader.
-force-vulkan
made the game work perfectly fine for me (minus a few pink areas towards the end of the last slope which I think shouldn't have been there), even though the error messages were still there.
