Hi. a) try playing with activating setUseDisplayLists(false); setUseVertexBufferObjects(true) on all your geometry objects. It really makes a big difference on Intel chips - not so much on nVidia. b) Reduce the geometry complexity of the stadium. The geometry is rendered twice because of your shadow casting - this is why reducing the vertex+triangle count will likely have a big impact. c) are you really sure the figure animation isn't done entirely by the CPU? there is just one osg demo "osganimationhardware" that uses a Vertex shader to animate a very small number of joints. All other demos I am aware of use CPU based meddling with transformation matrices. d) the 8500GT is a really old chip. The modern Intel offerings (HD graphics of the latest core i series) might already be faster. e) Aren't most of your characters sitting in the stadium ranks? You could replace these with animated billboards.
