Forward rendering performance drop for VR
Forward shading config settings as follows:
Scene is a typical outdoor scene with a Skylight sky and directional "sun" light. After turning on forward rendering render time went from 6.55ms (deferred) to 11.05ms (forward). I have attached the reference scenes (left is deferred) and the GPU profiles. The biggest leap seems to be in computing shadows... which I was not aware would be affected by switching to the forward renderer.
