It runs on my iMac with no noticeable impact on the computer. Activity Monitor shows it cycles between 2.6% and 3.7% of the CPU resources when set at the normal speed setting. If I bump the speed up to the fastest setting the CPU usage goes up to 5.6 to 8.3%. That doesnt seem like a heavy load … maybe Im wrong?? It sure is pretty with lots of detail. Lights come on as the sun sets and airplanes streak across the sky.
Its a keeper for me.
