Ken -

Thanks for the reply!  This is very exciting work!

The problems I'm having, at least on some of these machines, are multi-monitor related.  Everything works fine on one monitor, and I can see from the debug console that the OpenGL pipeline is enabled for only one screen.  I'm also seeing a nice performance increase!  Is there a way to enable hardware acceleration on two (or more) monitors?

Thanks,

Paul

Could I ask what the current status of this demo is?  I've tried it on a handful of machines (OS X, Vista 32, Vista 64, XP 32, with nVidia and ATI video cards), but I haven't had any luck.  On the windows machines, the demo window doesn't redraw at all.  On the Mac, the demo desktop is visible, and the Hello World sub-window is visible, but none of the demos in the Action menu work.

In general, in my own code, I've been having the problem that whenever the Java2d OpenGL pipeline is enabled, nothing renders into any lightweight Swing components (even when not using GLJPanels).  Disabling fb objects when using nvidia cards doesn't seem to make a difference.  I've tried a couple different JVM versions, with no luck.

Thanks,

Paul
