Human Factor - Java3D FSAA

Although Java is the best solution to networked applications (period), the 3D part is quite problematic. In an attempt to increase visual quality I activated full screen antialiasing (FSAA). This reduced the framerate considerately - close to 2-3 frames per second. This made med think that the library either does all calculations in software, or that the FSAA process is done in software. The few images I saw were a lot better looking than those earlier, but what about the speed?
