Well, I just move to using this driver as well and.... all is well...
polygon attributes no longer change the frame rate. Hmph, it was just the
driver all along. Still seems kinda funny. I wonder if anybody in the
Java3D team would care to figure out why...
Well, thanks for all your help.

Lee,
I'm running in 16bit with the 5382b08 driver from ATI's site.
When I moved to this driver, my performance increased noticably. This was
the most stable
and fastest driver from ATI that I've found for my video card. It's claimed
to be a 'beta' driver,
but if that doesn't bother you or you just want to try it, it can be found
at:
http://www.ati.com/na/pages/spdrivers/index.html
at the end of the list.
