I would love to use something like irrlicht and ogre. But at the moment
ogre is really slow. Since the newest rc1 release got reasonably faster but
it is still not thread safe. Irrlicht probably also uses legacy opengl.
Now the question is if I want to high performance scene graph with
threading support, should I choose openSG over OpenSceneGraph? And If yes
why?
