if you have a monitor with a refresh rate of 60, you wouldn´t see a different between anything above 60fps.Stop this debate, that has been proven wrong so many times... The eye may not be able to see it visually, but your brain can DEFINITELY tell the difference between 30, 60, 100, 150, etc. I play FPS games competitively and I can DEFINITELY tell the difference between 30 and 100, 60 and 120, 90 and 300. Don't bother saying otherwise.
