I am studying computer graphics at my university and I have a few questions 
about OSG.

Does OSG use the core profile? 

Are scenegraphs in general suited for games? Yesterday my professor said that 
scenegraphs are too expensive for games. (because of many state changes) 
Unfortunately he didn't mention an alternative. I also couldn't find any 
information about this topic. I only know that Ogre3d is using an scenegraph 
too. I also saw that there are many different implementations of scenegraphs, 
like BSP octree etc. 

Is OSG suited for a game engine?
