I decided to do some timing tests. Initially I just timed how long it takes for a MacBook Air to change from a simple black slide to a green slide. After ten tests, the average came out at 62.9 milliseconds. The next test was to determine if playing a 1080P HD Video Clip in the background affects the latency of the slide change. Surprisingly, this did not seem to slow dow the time it takes to change a slide. In fact, it was actually quicker with an average time of 57.6 milliseconds. The table below shows the results of this initial test and comparison.
