shader issue: with the default 'UseGLSL=enabled' setting, the game is either too dark, or objects, characters are plain black in the main game
What was not tested
everything was tested, I finished the game
Digital distribution version of the game, obtained via Gamersgate.
The game doesn't contain the Telltale launcher, it starts up without issues.
Only native d3dx9_41.dll was needed, it was placed to the game's directory by the installer itself.
One needs to disable GLSL via the following registry entry:
HKEY_CURRENT_USER\Software\Wine\Direct3D\UseGLSL -> "disabled"
Apart from that no other problems were observed, the game is fully playable.
