Johan, Your results are about exactly what I'd expect. Java 3D does basically require "modern" video cards. Video drivers must be current in general. We have had very little "failure" using Java 3D OpenGL but old video cards are pitiful performance wise (in general our testing has the OpenGL version of Java 3D solidly beating the DirectX version for performance - often at a two to one or better ratio).
Some video cards we've successfully run Java 3D on: Matrox G-200 - touchy about having the right driver and the right color depth to get decent performance. Matrox G-400 - troublesome all the way around, nothing to do with Java 3D (if the card works in that particular machine then Java 3D works fine). 3dfx Voodoo 3 - fine (but slow relatively speaking) GeForce - all versions run excellent - John Wright Starfire Research Johan Hedlund wrote: > > Hello > > I am currently developing an 3D-application which be used by people with > different video cards and many of them will not have special > 3D-accelerators.
