If there are 20 cameras in a scene and I need to capture the outputs of those cameras with different resolutions at least 15 fps. What would the best solution? In other words, if I have a powerful enough machine, can Unity render multiple outputs at the same time? What are the constrains? Preferably I don't want to split my screen and show the camera outputs next to each other and get the camera outputs, because in that case I am limiting my self to the screen size. The other way, would be capturing each output in one frame, for example, if the scene is rendered 150 fps. I can get 10 cameras' output, each in a frame. But all the mentioned solutions are not applicable for me. I even don't need to display the outputs. as far as I can store the outputs in the memory or file, it solves my problem.

Prepare:
Then in each frame do a loop through all cameras and perform this:
In general capturing one camera to disk is a slow thing, so capturing many will be a problem. Capturing to memory might be better, but you will fill your memory fast, unless your resolutions are small.
