The iPhone 14 pro is literally unable to play games because touch input causes massive amounts of stuttering. I showed it stuttering directly to a friend and he says it looks smooth. He could not see the stutter.Because not everyone has this issue. Which leads me to believe that it's a mix of both hardware and software factors. If everyone had this, there'd be a massive public outrage. I mean, people are not blind.
Some people actually can’t see stutters or frame rate drops at all.
