The big question I'd have is why on earth you'd have so many pre-render cameras. Why are trying to do with all of these? It may well be there is far more efficient way of tackling your problem. > I wonder if there is a way to make those prerender cameras render > parallelly? Without multiple graphics cards you can't do this. With a single card and single graphics context you can't render multiple times at once. Down on the graphics card the parallelism is all done at the vertex and fragment level, here it's massively parallel, but they aren't able to run concurrently multiple graphics threads/contexts.
