FWIW, on my Mac I put some timings into the display code and from the moment we receive a keyDown notification to the moment we hand off the drawn buffer to the system for display takes around 3-6ms, so unless Aaron's system is very different from mine, most of that time is spent in places we can't do much about. -- Alan Third
