The new 8x, 12x and 16x Anti-Aliasing on GeForceFX at 3DCenter.org

"In conclusion nVidia now offers seemingly higher anti-aliasing modes than ATi (6x maximum), but they do so with mostly ineffective subpixel grids, especially in the highest settings. This way these modes eat a lot of performance and impress with their names, yet they are not (or at best marginally) better than 4xS, which has been introduced with the GeForce4 Ti and is also available on GeForce3 if you´re using a tweak tool.

8xS anti-aliasing is the only mode that really exceeds the quality achieved with 4xS and it´s the only mode that can compete with ATi´s 6x anti-aliasing. Strangely enough nVidia´s Detonator control panel only exposes this mode for OpenGL, and offers a clearly inferior 8x mode for Direct3D. A tweaking tool like aTuner is absolutely required to get the better one of the two 8x modes for Direct3D, at least at the moment.

With the higher-labelled 12x (Direct3D) and 16x (OpenGL) modes, nVidia seems to have missed the mark: Both offer little if any quality gains beyond 8xS. The 16x setting under OpenGL also performs worse than 8xS. And of course the 12x mode for Direct3D bears the name "16x" in the Detonator panel. This is completely unjustified and needs to be corrected."
