Cameron Hummels:

Right now the PerspectiveCamera is about 4x slower than the PlaneParallel Camera in the VR interface.  PerspectiveCamera is the most intuitive framework for doing VR since it behaves well to moving a camera in a volume and rotating that camera, and it would be great to use it as the default Camera.  However, right now it is too slow to use for regular operations.
