Hardware planes will hopefully reduce the latency again as it will allow windows to skip the compositor and allow mapping parts of the framebuffer to a window buffer.
I believe there's some work on Linux already for them, but I'm not so sure on Windows. I would be surprised if macOS doesn't already use them in some capacity given Apple's obsession with delegating everything to firmware on a co-processor.

Hardware planes are great but there are a limited number of them. Right now I believe Windows only uses them for the mouse cursor, and exclusive fullscreen.
