Scott,

in neither of these versions I see you actually checking whether your text is visible in the view. So, I just thought I'd mention again: The best way to speed up drawing in Cocoa is to not do any drawing at all.

Characters are very complex shapes, so a check whether two rectangles intersect will always be noticeably faster than drawing them and waiting for Quartz to check each pixel against the clipping path to find out it doesn't need to draw.

If your view is inside a scrolling view, for instance, you'll end up doing way too much work for what the user actually gets to see. -- Cheers, M.
