16bit OpenGL rendering can use a form of dithering where the lack of colour depth is hidden by rounding different ways depending on the pixel being drawn. Setting to 0 can theoretically be faster or less hideous. Then again, it could look more bland. It depends on personal preference. It has no effect at 32 bit depths.
Enables OpenGL dithering (16bit looks bad with this off).
