i agree w/feldon re: poly normal calcs and fps. the higher the fps, the smaller the delta (movement in 3dspace) between frames, so the eye's perception of the movement "smooths out" like he says.
cjmaddy, i had an old ssytem w/an old video card and a slow cpu not too long ago. i never got more than 25 fps and the aquarium looked great! i couldnt explain after i upgraded whether it was the fps, the OS, the new card's capabilities, the new version of DX, or what, but what feldon says explains it all now
