Dear OSG Community, I'm developing visualization software, which involves rendering of large point clouds. I optimized the scene graph in order to get better frame rates. In particular I now use osg::Geometry instead of osg::ShapeDrawable.
I tested it on 2 different machines and got different performance gains. System 1 (Notebook): Intel Pentium-M, 1.86GHz, 1GB RAM, Intel GMA900 Chipset, Windows XP System 2 (Desktop PC): Intel Core 2 DuoE8400, 3 GHz, 2GB RAM, GeForce 9500 GT, Windows XP On System 1 the rendering is about 40% faster with the optimizations. And on System 2 I got a 7x higher framerate ! Now, my question is: what can be the reasons for that dramatically differnet performance gain? I suppose, it is because of the different OpenGL implementations and graphics hardware, but I don't have a clue whats really going on here ... Who can give me some comprehensible explanations? Thank you!
