Thanks for both replies.
However, neither are helpful. As the second poster pointed out, the fact
that the Creator and the Elite have lousy texture performance is
irrelevant: I'm using both and Elite-m6 and an Expert3D ... the Expert3d
is the OEM'd Intergraph Wildcat 3D card, which should have excellent
performance. But, it has WORSE stutter problems. The quality of the card
is probably irrelevant because, as I said in the first message, this is a
program that spins 1 (one) textured polygon. Even the Elite can do that.
As for raising the priority, that also is not the problem. This is a
dual-processor Ultra-60 (dual 450 MHz), and the only things running are the
X server and the j3d process. Neither are coming close to consuming either
processor.
Finally, my own non-j3d program can spin a polygon smoothly with no problem.
So, clearly, it's a java-3d problem.
