I've manually set that to YES using IB3, and it did make a significant difference in loading time, pretty close to the near-instant time of TextEdit. However, when I try to scroll through the NSTextView using the scroll bar, it often becomes unresponsive. I'm assuming this is because only at that point is it rendering the layout for every section I scroll past, which would make sense. Though, TextEdit doesn't show this same behavior. So, I think it's a step closer!
