What's it do?

It is another form of texture filtering. It helps improve the look of textures in a 3D image by accurately rendering the texture based on the angle of the texture in relation to the camera.

However, if arbitrarily applied to a texture that needs point filtering, it can cause the texture to blur due to rounding errors in the color calulation/sampling.

Ah, thanks

Does AH support this?

It is not used by AH. The effect it has is really best witnessed in long corridors or in tunnels.

Enabling it causes a performance hit for the video card, and in AH will blur all the text.
