Just a guess, but I think that the ATI Rage series only support hardware
acceleration if you're at 16 bits per pixel. Otherwise it's done in
software.
(Of course this is not helpful at all if you're already at 16bpp)

I've got the same graphics card he does, and I don't seem to be getting any
acceleration either. I've got the latest drivers installed, if that means
anything.

Subject: [JAVA3D] Java3D Performance Help
Hi guys. Is there any way to speed up Java3D's
rendering performance? I know using hardware
acceleration is one way. My config is as follows:
P-II 450Mhz
256MB Ram
Ati Rage Pro 3D AGP 2X
JDK 1.2.2
Java3d 1.1.3 for OpenGL
Windows NT 4 Service Pack 3
How can I tell if the 3d card is being used or not?
Right now I am getting maybe 15fps in my application
(and this is with no textures). There are about 200
shape3d nodes which are lit by a directionallight
and ambientlight. I also see the hard drive light
flicker constantly while the app is running(all other
apps are closed). What is going on? Also, would
reducing the number of shape3d nodes be any use?
Any feedback would be appreciated (esp. on using
hardware acceleration which seems to be essential for
OpenGL). Thanks.
