34 minutes???? you must be kidding! That cant be right can it? My fairy lights are over 10 universes and each universe has almost 500 channels, each string (universe) is broken up into 5 pixel groups and drawn in the visualiser as a line spread over 5 pixels. As these strings come out over the lawn, I have pretty much drawn each one on top of the other. I have a core i7 with 16gig ram, and to render a 3 second colour slide macro, it took 34 minutes (and there were errors!) This can't be right can it?
