Lan, Your TNT2 chipset is getting a bit "old". Newer video cards can deliver significantly better performance. During our development with Java 3D we noticed significant improvements as we stepped from Matrox G200s, thru Voodoo 3s to GeForce cards. The TNT2 is about on par with a Voodoo3. With a GeForce 3 or 4 I could easily believe someone getting ten times the performance that you are getting. (especially if you're running a PCI not AGP interface).
But the type of 3D scene makes a big difference. If you have lots of vertices you'll need CPU and RAM memory, if you have huge textures you'll need a powerful video card with lots of video memory. If what you two are running is 90% CPU bound, not video card, then you could upgrade and see very little difference. Perhaps Nitin also has a faster CPU? - John Wright Starfire Research Lan Wu-Cavener wrote: > > Hi, everyone: > > I just realize this and would like to hear other experts' comment. > Several days ago, Nitin Jain posted a test code which rendered 1000 > spheres.
