Sorry if there are already threads on this. But I have an almost maxed out 2013 iMac, Airport Extreme, Apple TV, and Mavericks. I have tried to use airplay from my mac to my tv and it has an unwatchable framerate. All softwares have the most recent updates. Is this normal. I mean whats the point of airplay if the framerate is unwatchable. I have tried switching the resolution to 720p from 1080p and it doesn't help. Major disappointment if you ask me.
