    Hello guys...

    for anybody who uses Airplay in ML.

    How much does it use CPU wise

    a) normal Audio-streaming using Airplay as the Audio Device for everything that the mac is playing
    b) when mirroring the display + audio.

    Can somebody say how many miliseconds the latency is when using airplay?

    No latency for the Audio, can't check Mirroring because i only have AirServer which doesn't support ML yet.

    how about cpu usage or temps while using Airplay Mirroring?

    I'm very curious about this too. I read somewhere that latency for mirroring was about 100 milliseconds. That's enough to notice, but not enough to matter.

    As for CPU usage, I'm stumped. Supposedly, it will use intel quick sync, which is more efficient and reduces overhead compared to streaming frame-by-frame screen captures. Still, I doubt that it won't have a noticeable overhead.
