It's quite obvious that on regular PS4 it will have to run sending half of the total pixels and polygons it can produce to each eye. This means that a game running at 1080p maxing out regular PS4 would run at ~760p per eye in VR. With some optimizations, it could probably run at a higher res, as each couple of frames of VR is a different projection of the same scene, so a lot of the input of the GPU is the same for both, saving bandwidth and lowering the graphics RAM miss rate, so allowing the GPU to run closer to its ideal performances and reducing framerate drops.
