We recently bought a NEC Versa latop (the highest end model) because it had
the Savage/MX chipset, which is supposed to be one of the best chipsets for
3D on a laptop (same league as the Rage128, far better than the other Rage
Mobility)

Our experience is that J3D runs terribly on this machine.  As a comparison,
if we run Quake3 (an informal OpenGL benchmark :-), and put it in 32bit
mode, we get a frame every few seconds(!).   If we put it in 16 bit mode,
it starts running smoothly _until_ there are too many textures (our
interpretation of what is happening) visible.   We had to go to medium-low
quality textures to get it to run smoothly at all.

My suspicion is that J3D is simply choosing a visual that is poorly
supported by this platform.
