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
