    I'm wondering if Apple could use the second unused GPU, and perhaps one core of the CPU if needed when Airplay Mirroring so that there is little to no performance hit when Airplay Mirroring at 1080p.

    Anyone know about this? Similarly, shouldn't there be a way to utilize the second GPU for heavy tasks? Is this impossible because of power, thermals, software?

    Do you mean on hardware that doesn't have quicksync? the machines supported with Airplay Mirroring use quicksync so there is no performance hit.

    Intel's Quicksync enables hardware based encoding but it does not happen magically, it still requires effort from the CPU. But perhaps your point is that neither GPU would be leverage to help with the task?
