Apple introduced the 120Hz refresh rate on the flagship. With the new refresh rate, it is up to developers to update their apps for the user experience to climb to another level of smoothness. Today, Pokémon Go has been updated to take advantage of the higher 120Hz refresh rate displayed on the new iPhone 13 Pro and iPhone 13 Pro Max. Scroll down to read more details on the subject.
