FSAA & Image Quality Comparison - 3dfx vs ATI vs NVIDIA

Level of Detail (LOD) Bias

We investigated the effects of the various LOD settings on the Voodoo5's FSAA image quality in our final review of the Voodoo5 5500 from a few weeks ago. For an in-depth description of how to enable the LOD slider and what it does, visit our Voodoo5 5500 Review.

Below we have the top half of two screen shots taken from the same location, once again at 640 x 480 x 32. The upper most screen shot illustrates 3dfx's 4 Sample FSAA at its default setting, and the bottom half is the same shot, this time with the LOD slider set to the -8 position.

As you can see, the 4 Sample FSAA with the LOD slider set to the -8 position really sharpens the image up when compared to the default LOD 0 setting.
