One thing for sure is to rotate view, not all objects. I've done a bit
of profiling on program and it was transform3d compute bound. When I
changed all mouse behaviours to OrbitBehaviour on view, performance
increased about two times.
Second thing I've done is switching from directx to opengl. Performance
increased threefold (six times compared to original measurement).
I hope it is enough for the moment. If you would like to make it faster
by another factor of six, please tell :)
