I notice that even when the SimpleUniverse I'm using doesn't have focus, it still uses a lot of CPU. If I minimize the frame though, it uses almost no CPU. Is there a way to "freeze" a scene when the window loses focus, to free memory for other applications, or windows w/in the same application?
I have +1 viewport for the same data, and the user can bounce around window to window. But the j3d window slows everything else down unless it's minimized.
Thanks for any suggestions,
