  Ah yes, I remember this. Worth noting that his device is a projector putting the image on a screen, and I think it's got a lot more computing power behind it than an iPad has available.

    The current latency isn't a CPU issue though. I'm not sure of the refresh rate of the iPad (60Hz?) but the hardware has no trouble updating the display in a single frame. It should be noted that unless Microsoft had a 1000Hz display running, there was something fishy going on with their 1ms update.

      It's a custom display purpose built for this demo. I believe that it is 1000Hz.

      From this high speed video I took I think the refresh rate is 60Hz (this shows it is at least 60). http://owenimholte.wordpress.com/2012/03/30/ipad-3-screen-refresh-example/ http://owenimholte.wordpress.com/2012/03/30/ipad-3-screen-re...
