I saw this performance regression using SpriteKit in iOS 9.1 and was hoping this would be resolved in 9.2 but it is not. (Worked fine in iOS 8) There is a slight (1s) screen freeze when switching between view controllers. I am using buttons and segues in the storyboard to transition between VCs. The screen freeze coincides with this error message:
2015-12-09 19:53:06.991 Game7[411:91125] : calling -display has no effect.
I have read about explicitly setting the zpositions of all sprite nodes to improve performance but this does not seem to help. Any guidance would greatly be appreciated.
Thanks
