Why doesn't Pete's OpenGL work with my Voodoo3?

anyway, I think Voodoo3 3k doesn't have FSAA for the antialiasing, but the Bilinear Filtering does its job pretty well. But can anyone describe the difference between AA that done by FSAA and BF?

I don't wanna get into explaining the processing algorithims behind the FSAA technology, so this is sorta a simplified version.
Well, FSAA takes the whole scene, and re-renders it to a higher resolution, i.e: 640X480 image gets boosted to 1024X768 image. Now, this resolution boost is done in the cards memory, before it gets sent to the monitor. The edges are smoothed as a side effect of boosting the resolution. Then, the card lowers the resolution back down, i.e.: 1024X768-->640X480 image. The new, smoother image is then sent to the monitor.

Bilinear filitering simply smooths the pixels together for a "neater" look.
