I'd say this is something that can be done on a driver / GPU level; if the inputs to render the next frame are the same, it can just reuse the previous one.

That's probably oversimplifying it, I don't know anything about graphics programming.

This doesn't really work. By the time the driver or GPU could "know" that the frame is the same, it's already done a lot of the heavy lifting. As in, it has basically still rendered the next frame by this point. Actually writing the result to the framebuffer is not expensive.
