Just got word from 3dcenter.de that they have found three new anti- Aliasing modes in Nvidia detonator 42.01.....Here's a quick translation as the sites in German

By coincidence we are discovered that nVidia's current detonator 42,01 already has three new anti- Aliasing modes: 4xSS, Sx4 and 6x, usable with GeForce3/Ti and GeForce4 Ti. and natural we had to examine these new modes for their structure and their effectiveness.
