Gold, I tried the skull demo without auto rotation. However, I do not see an increase in real fps when comparing 3.2 to 1.6Ghz. Try this, maximize the screen so that you get very low fps. This way an increase in fps will be very noticeable when downclocking the cpu. When I do this, the image is just as 'jagged' in motion when dragging the skull with the mouse, regardless of CPU clock speeds, although the demo's fps is twice as high.
