Anti-Aliasing and Anisotropic Filtering
Since the early days of the Radeon 9500 boards, AA has been the special area of the ATI based products. Even the newer versions of the nVidia product line are just now getting to an acceptable level of performance in this area.

It gets rid of jagged lines and makes the overall appearance look like what you would see in a CG movie scene. The only problem with this is the performance hit you get when creating this improved visual scene.
So, knowing we'll be taking a performance hit, the goal is to be able to use these rendering techniques but still maintain a playable gaming scene without having a terrible frame rate.
