4dplane YaBB Newbies Offline Posts: 45	size(1000, 1000); Draw runs slow Feb 25th, 2006, 8:03am   Hi, I have a simple sketch that runs many times faster if I set the size to (200, 1000) - why is this and is there a way around it? Thanks, 4dplane

The technique not always draws the whole screen at every loop, but only the parts that change.
