Now let’s look at the screenshots from NVIDIA GeForce 6800 Ultra. First comes High Quality mode, then Quality mode, then Performance and then High Performance:

It is really hard to notice any differences in image quality on a static picture. However, in dynamics in Performance and High Performance modes you can see how sharply the MIP-levels change, because of the aggressive tri-linear filtering optimization.

If you look at the images with highlighted MIP-levels, you will notice that on the transition from “quality” to “performance” modes MIP-levels of the second texturing layer get closer to the camera, which indicates that the LOD is getting lower or that the maximum anisotropic filtering mode imposes certain limitations.

Finally, let’s take a look at the results of NVIDIA GeForce FX 5950 Ultra. First comes the Quality mode, then Performance, and then High Performance:

Quality mode	Performance mode	High Performance mode

Since NVIDIA GeForce FX 5950 Ultra supports only 8x anisotropic filtering, the textures on the farthest MIP-levels appear less clear, than by the previously considered graphics cards. All optimizations are enabled: tri-linear filtering degradation, reduction of the maximum anisotropy level in the most high-performance modes.
