Well, the simplest one would be "prioritize whatever talks with input devices and video card"

I guess the hard part would be distinguishing between "a video game getting inputs" and "discord app getting push to talk key", but at the moment you moved all of the noninteractive system stuff to slow cores and only "things using keyboard" on fast cores it's already pretty good approximation.

Not every game benefits from it as well (vs higher core clocks), so it's not really a comprehensive method.
