But you'll ultimately want to profile things especially if your text changes often. For example, for text that would only live for a single frame, you may find that rendering text to an image followed by blitting that image may be slower than just rendering the text directly.

And, while it doesn't use cached NSImages, definitely check out the following example as it demonstrates a few approaches in obtaining better text performance:

Thanks for the pointer, Ricky. The layout of my text is changing pretty much continuously, using most of the screen, but the content is relatively static. So I'm hopeful that using the layout manager to cache the glyph rendering info will be the bit of magic I've been missing here.
