Hi,
I think you can find some answer here :
http://www.j3d.org/implementation/properties.html
 because some features are optional due compatibility.

I think Java3D 1.3 is mainly  upon OpenGL 1.3...

Subject: [JAVA3D] Geometry performance on D3D9 hardware


> Under Direct3D9 hardware, what are the relative performance of plain

caches?
