I ran a Heaven benchmark today on my macbook pro 2015 to see what it was capable of, but whilst running it I noticed that the onboard graphics were nowhere near maxed out and the screenshot of activity monitor shows it was only running at 2/3 of what it could be? Is there some trick here or does apple limit the performance. I tried putting the fans on max speed manually but this made little difference. Any thoughts? screenshot of activity monitor
