about 120 fps in iphone 12 pro max problem

I am facing a problem in my device iphone 12 pro max why there isn't 120fps enable anyone can say me?

Solution

All iPhones and iPads that support 120Hz refresh rate have the 120 FPS option available. As iPhone 12 Pro Max only has a refresh rate of 60Hz, it unfortunately cannot support Extreme+ and Ultra Extreme Frame Rate options in PUBG MOBILE.
