Jim,
I don't agree with this. I do agree that laptop performance is still
not going to equal desktop performance, but I KNOW the Mobility 128
provides decent OpenGL hardware acceleration. When I first started my
applet on the 5000e, it ran very slow and I could tell it was not
hardware accelerated. The framerate was very slow and the textures did
not look very good. Then I switched to 32bit mode and saw a DRAMATIC
difference. The kind of difference when you can tell that you are
getting hardware acceleration, i.e. smooth navigation, smooth textures,
good FPS, etc.
My applet displays a moderately sized scene with large textures,
interactive mouse-dragging navigation, randomized lighting effects (a
fire light), all being updated better than 30 fps (don't remember the
actual fps).
What color mode did you run your benchmark in?
I tried running in DirectX and had no problems that I can remember, but
stuck with the OpenGL for demo purposes just to be safe.
My machine: 5000e, 16mb ATI Mobility 128 AGP, 256MB, Win2K, J3D/OpenGL
1.2
The Geforce 2go sounds interesting... hadn't heard of that one....

Subject: Re: [JAVA3D] Windows 2000 Performance.
To add my 2 cents to this issue:
Have run benchmarks on both Dell Inspiron 5000 and 5000e. Here are my
results using Win2K on both platforms:
1) Both machines fail about half the J3D benchmarks I tried with the
Java3D 1.2 DirectX version. "Fail" means fail to run, black screen
and/or crash the JVM. Those benchmarks that actually ran did so
much faster than the corresponding OpenGL-based Java3D benchmarks.
Unfortunate that the DirectX implementation (as of J3D 1.2) is
apparently
not quite all there yet....
2) Both machines ran my benchmark suite correctly with the OpenGL
version
of Java3D 1.2. Performance: about 20% of the speed of a NVidia GeForce
2 MX
on desktops with similar CPU (700-750 MHz PIII/700 MHz Athlon/800MHz
Thunderbird) for benchmarks that were limited by the speed of the 3D
engine.
My conclusion: Dell still does not support hardware acceleration with
Java3D,
or their acceleration support is inadequate.
Is anyone aware of a laptop available yet using the NVidia GeForce 2Go
chipset?
Thanks-
Jim Schatzman
