HQV Noise Reduction/Motion Adaptive Noise Reduction Tests

The noise reduction tests basically show the level of noise reduction applied, and if so whether there any loss in image detail or not. The motion adaptive NR tests how well NR is applied to moving objects; how blurry they are, and how clean the background is. ATI did a much better job than NVIDIA with both of these tests. NVIDIA seemed to apply little or no NR, although to their credit, the motion adaptive tests showed little blurring or smearing to the moving objects. The sky, even in the motion adaptive test, was always very noisy on NVIDIA hardware. From the images, we can't actually see the noise reduction as it is a temporal issue, but the motion noise reduction is very easy to see.
