Jaggies Tests

The three Jaggies test evaluate how well a video processor is at determining whether objects are moving or not. The first "jaggies pattern" is a simple spinning bar, the second "jaggies pattern" is a set of three bars with a waving motion (like waving your hand), and the third test is a real-world picture of the American flag in the wind. These all represent scenes that a deinterlacer will easily be able recognize as having motion.

Catalyst 5.13 improves ATI's performance on theses tests substantially. Whereas NVIDIA develops jaggies in the yellow zone, both ATI and XGI are perfect with their diagonal interpolation.

Under Jaggies 2, all three properly smooth the first two bars, but none are able to keep the third line smooth.

Although all three earn the same numerical score, ATI and XGI do better than NVIDIA in preventing the aliasing in the third bar.

In the real world flag test, ATI does an excellent job. It appears to detect edges a little bit better than the XGI's approach, resulting in fewer jaggies. Both XGI and ATI are substantially better than NVIDIA. Although ATI's Catalyst 5.13 still shows some very minor aliasing, it takes careful A/B scrutiny between ATI's Catalyst 5.13 versus DCDi or HQV to see the difference. ATI seems to fall behind just a hair compared to the HQV processing, but since our testing is done at 1280x1024, it's possible that the differences are due to the video scaling portion. For the flag test, ATI receives the full 10 points.

Score:
1st place: ATI (18 points)
2nd place: XGI (13 points)
3rd place: NVIDIA (11 points)

Interpretation:

When it comes to de-interlacing 30 fps content such as TV shows, the ATI Radeon X1800XT and XGI Volari 8300 are superior to the GeForce 6600.
