Good point: If we have to render a single 3D frame with 2N pixels and 2P polygons, it will be more demanding than rendering two 3D frames for VR (or for stereoscopic 3D, the maths involved are the same) with N pixels and P polygons each, as being two different projections of the same scene, most polygons will be the same, so VR will save bandwidth and will also need less CPU power and less system RAM, having to manage a less complex scene, while even without possible VR optimisations, the GPU will already be able to use its computing power more efficiently and at the highest overall res VR could still avoid CPU, bandwidth and memory related bottlenecks that would start affecting the same GPU rendering a single scene with twice the complexity of each VR frame. |
That's why waiting for proper reviews, and from more than one site (to avoid biased reviews), is always the more sensible thing.
