"Fascinating comments from OnLive this week, courtesy of CEO Steve Perlmen, including a very helpful definition of what latency is and how little of a factor it is with OnLive. 'The round trip latency from pushing a button on a controller and it going up to the server and back down, and you seeing something change on screen should be less than 80 milliseconds,' Perlmen told the BBC. 'We usually see something between 35 and 40 milliseconds.'
He then went on to say that latency and frame rate are independent factors. True up to a point, but a screen updates at 60Hz, meaning that measurable latency has to be a multiple of 16.67ms (1/60th of a second).
So how do you actually measure latency then?"
