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.
