New Driver / Update Description:
The Revolution 3D cards used for driver development exhibited a slight distortion on screen under the following display modes:


The distortion causes the right side of windows to undulate. This is most noticeable on a text filled window with white background. This seems to be caused by some unknown hardware problem on those cards.
