Hi All, I've just been asked a question which I know nothing about and was wondering if anyone here can help. I have a friend who is a DJ, and uses his Dell Windows laptop on his gigs, think he stores his music collection on it, as well as controlling the lights and lasers. Anyway he explained to me that he needs to get his DPC latency down to below 100ms, which apparently is extremely difficult to do on Windows OS, as it's not a "real time" operating system. What is the situation with Macs? is there such a thing as DPC? and what would be the latency, on say, a 17" core i7 MBP? Thanks, I know it's a strange one, but thought I'd ask the experts here.
