NVIDIA GeForceFX 5900 Ultra: The Way FX is Meant to be Played!!

Aniso Image Quality

Instead of giving you a full image quality comparison here, we decided to postpone it to a later article, especially in light of the fact that ATi has announced the release of a new, highly optimized driver (Catalyst 3.4) within the next few days. Nonetheless, we'd like to show you a few screenshots we took in a program called Aniso Tester .

In the mode you see in our screenshots, the program displays a tunnel and highlights the filtered areas. Also, the number of walls that make up the tunnel, and consequently the number of viewing angles, can be set by the user.

With the help of this program, we can easily see how the individual quality modes do their filtering. It also helps us find angles at which drivers switch to another filtering level.

Here you can see a few screenshots comparing the NV30, NV35 and Radeon 9800.

The app renders a tunnel, here with five sides.Then it adds maps with aniso filtered texture to it. Perfect to see which filtering is applied to certain angles. We will use a full circle.

NVIDIA has completely reworked the filtering method in the Detonator FX driver. While the old driver only uses a bilinear anisotropic filter for the most part in Quality mode, the Detonator FX offers excellent filtering quality.

The filtering modes of the old 43.00 driver leave a lot to be desired.
