I noticed the gui where the 3 sliders are for Image Quality, AA, and AF are like the old driver sets, instead of in a little window where it has the check box underneath for Other Options...like GL Conformant Clamp Behavior and Force MipMaps to None, Bilinear, or Trilinear. Seems that this coolbits is a cross-between old and new.
This coolbits.reg file seems to keep whatever settings the drivers you are using is supposed to have. I didn't gain anything from yours, but didn't lose either. Not flaming, just FYI.
