The killer feature of the iPhone 12 Pro has just been revealed in iOS 14

The iOS 14 developer beta is available, giving users the opportunity to try out exciting new features like widgets and the App Library. But it may also have revealed a great display update for the upcoming iPhone 12.

Featured concept artist and filter-bender Ben Geskin posted a screenshot of the iOS 14 accessibility menu that appears to have a new “Frame Rate Limit” option. According to the description, this option “sets the maximum frame rate of the screen to 60 frames per second.” But since the current iPhone 11 series is already limited to 60Hz, this could be a sign that Apple is gearing up for faster 120Hz displays on the iPhone 12.
