Hi Niel I have not tried this myself, but I remember that support was added for manually handling the render loop.
OSG will default to a render loop that follows your screen refresh, and if this is forced off it will redraw as fast as possible. But i think there is support for handling when to initiate the redraw from within your application. If you do this CPU usage should go down drastically if you don't have to redraw often. There should be some discussion of this on the mailing list, but I don't have a link so you will have to do the digging yourself. Brgs.
