--- Comment #18 from MC Return mc.return@gmx.net --- I noticed though that the OpenGL Shading Language and Shadow Quality options in AstroMenace's Advanced Video Settings are not available (red), while the log shows no problems. I do not remember if those settings could be activated in previous versions of the game though and if they are even implemented... maybe someone could also check that ?
