Resolution Note:
On iPhone 13 Pro when the ProMotion is enabled and app is running on 120 FPS it drops to 60 FPS for the single frame where initial touch happened. This is coming from OS and we can do nothing about it. If the spikes are interfering with an app in a meaningful way you can disable ProMotion functionality for the app by deleting CADisableMinimumFrameDurationOnPhone and CADisableMinimumFrameDuration keys in the Info.plist of your app.
