Hi Tim, As Sebastian mentioned the internals of osg::Geometry have been cleaned up to remove all the old OpenGL slow paths, there is no a lower CPU overhead so typically I'd expect better performance from this part of the OSG.
Seeing higher GPU costs would suggest something different is being sent to OpenGL, perhaps some optimizing of the scene graph is being done differently. There weren't any reports of slow downs that I recall in the run up to OSG-3.2. Given this I would suspect a particular dataset type that isn't being loaded differently. As I know nothing about your specific data I can't say anything more other than ask more questions. What type of data do you have? What formats are you loading the data from? Are the scene stats similar? Number of vertices/Number of Drawables etc. Does osgviewer also work slower on your system? Robert.
