Hi Mike,
I had posted a test app that
prints out the frame rate to the console window.
please run this app (by launching the attached helloUniverse)
and post the results on list
(I have had many many
difficulties with J3D and win2k; you can search the mail archives for a previous
email titled "BUG?! Java3D Performance issue on
Win2000")
Thank you, SyrusM
