FWIW, AirPlay can send a H264 video of my desktop at 60FPS with ~0% CPU impact (hardware accelerated), good enough to play many games on TV.

I believe Airplay has special OS integration - a third party app wouldn't have access to the screen buffer with zero-copy.. A third party app would at a minimum have to copy the data to system memory and back to the GPU, using a lot of CPU time for that alone, before any encoding.
