I was wondering what the refresh rate of the human eye is? I was had been told that the human eye cant see more than 40 Frames Per Second.... And heres a nice way to test it: 1. Hold your left or right hand wide open, so that the back of your hand is facing you.... 2. Make sure your looking straight on at your fingers 3. Move your hands rapidly left and right 4. Keep looking at your fingers Now you will in fact see the so-called GHOSTING effect that we are familiar with on LCD monitors... that means you will see a kind of trail left behind... due to the fact that your eyes arent able to send more than a certain amount of info to your brain! Now im wondering how much that certain amount is... basically what is the refresh rate or response rate of the human eye! And heres ANOTHER question... if we have a limited vision in frames per second, why are we obsessed with higher FRAMES PER SECOND in games!
