SpriteKit low fps scene at startup

Question

My problem is that my GameScene starts with doubling the nodes and the number of hits and 40 frames per second in a few seconds. This problem only appears on my iPad (mini retina), while on my iPhone (5) the game runs smoothly from the very beginning, although the nodes are still much larger than what should be

Answer 1

This 40fps issue is an issue within iOS. It was created by some kind of throttling (iOS).

Perhaps this throttling was designed to give a more consistent experience for an application struggling to maintain 60 frames per second. But no one knows.

Apple has never commented on this.
