Alex,
As far as I know nobody has tried to systematically benchmark Java 3D.
We have tested and compared our application on several systems (GeForce
256, Matrox G200, Matrox G400, TNT, TNT2, Voodoo 3, ATI, laptops) and
the GeForce generates a huge improvement (2x to 4x) over the others but
otherwise the real difference is whether or not you get hardware
acceleration (which can be just a matter of which video driver version
you are using or even just the wrong color depth). All of our tests so
far have been with AGP but in the next month I do intend to try a PCI
Voodoo 3.
Certainly bus speeds and other hardware tweaks may make some difference
but they are usually hard to even measure. As far as Java 3D goes my
opinion is that the most critical factor that matters is whether or not
you are obtaining hardware acceleration or not (makes about a 20x
difference).
I'd be curious to know more details of the relative performance of
OpenGL vs DirectX implementations of Java 3D. Six months from now we
will need to know which to install by default or recommend to users.
