So I fired up Real Racing II HD over Airplay Mirroring last night (on the new iPad), and basically it was half ok / half slide show.
The game would be smooth for 5 seconds, then 5 seconds of slide show / stuttering, then good for 5 seconds...rinse/repeat.
Infinity Blade II ran just fine with no hiccups, and I also have no issues with video playback...smooth as butter.
Naturally, when not running on Airplay, the racing game runs perfectly fine.
Anyone else try to run RR II HD yet over Airplay Mirroring with the new iPad?
