Anisotropic-Filtering (AF) is an other method used to offer qualitative textures in games. This method has to do with textures, making them sharper and more clear. In the past there were other similar methods like Biliniar and Triliniar Filtering but Anisotropic is the latest and till now the most powerful texture filtering.

The X800 XT uses the following AF levels: 2x, 4x, 8x and 16x. Again I picked stage from Doom 3 to capture a particular texture scene with different AF levels.

	AF OFF
	2x
	4x
	8x
	16x

At the 8x level the marble textures in the back are most clear as there is very little difference between the last 2 levels.
