Christian Selig on Twitter: "Yeah, seems to be the case. Sample project where I move a box across the screen with UIView.animate only gets 60Hz/FPS on iPhone 13 Pro (same as iPhone 11), but UIScrollView gets 120Hz/FPS. (See attached, from Xcode Instruments, 1/60 fps = 16.6, 1/120 fps = 8.3) Wonder why.… https://t.co/yt723QUqlb"

Am I correct in seeing that UIView.animateWithDuration APIs aren't clocked at 120Hz on iPhone 13? On UIScrollView, system ones, and Metal by the looks of it, rest is still 60Hz?pic.twitter.com/t3MeM9cj0E

Some workarounds attempted: Using property animators (UIViewPropertyAnimator) instead, still 60 FPS. Hardcoding 120 FPS with UIView.animateWithDuration doesn't exist unfortunately, only options are 30 or 60. Quick someone write an animation engine in Metal. pic.twitter.com/czhVYV0Imu
