The screens really don't do the textures justice. The modulate/intensity levels you have there make everything look pale. The intensity filter is particularly evil, it basically halves your color range with the default value of 2.0.Have you thought about doing away with intensity and adding proper brightness/contrast? I have code for this right here, it also includes a saturation filter, as well as monochrome and inversion controls:http://jdolan.dyndns.org/trac/browser/quake2world/src/r_image.c#L281
