Disabling Vertex Shader or Pixel Shader fixes this, however: no Vertex Shader causes PWI to crash after entering the game world with some video cards. no Pixel Shader causes the 'Everybody is Naked' bug.
This worked for me, Using the latest git, I turned off vertex shaders and the bug doesn't appear. My graphics card is a 7900GTO, and it didn't crash on startup.
