This test simply shows a few rotating lines in a circle. As the angle changes, interlacing makes the lines appear to become stepped. Successful de-interlacing will remove these artifacts.

The Radeon 2600 XT gets full points here, and the 8600 GTS does well - but only in Windows Vista. The other cards are completely unsuccessful.

Film Resolution Loss Test: Out Of 25 Points

This test simply shows a pattern of lines and color bars. If the DVD player can show the smallest lines without flickering, it is successfully de-interlacing the image.

Can you see a pattern here yet? Flawless 2600 XT performance across the OS options, the 8600 GTS works in Vista, and nothing else works at all.

I'd like to note that I did see a tiny bit of flickering with both the 2600 XT and 8600 GTS in some of the lines on the interior of the test pattern, although the HQV benchmark's scoring guidelines state that I should only concentrate on the corner boxes. Since these did not flicker, I gave perfect scores to the 2600 XT and the 8600 GTS in Vista.
