new OpenGL-based pipeline for Java 2D
According to the rhw Java Buzz Forum there is a binding to OpenGL in Java 1.5 enabled by adding the VM argument-Dsun.java2d.opengl=true
I must try this to see if it improves the performance of our Java app that does a lot of image movement on the screen.

Update: Yes it does significantly inprove performance. Our app went from using 100% CPU to using about 40%, and image animations are smoother. However it reduces the colour depth to what looks like 8 bits, which is not acceptable for displaying photographs in our application. Also it seems a bit buggy, crashing the JVM on exit for example.
