CATiledLayer in iPad retina simulator yields poor performance

Question

I\'m hoping maybe this is just an issue with the simulator but of course it has me worried since I have already submitted my retina capable apps and there\'s no way to test

Answer 1

CATiledLayer performance on the simulator seems to be nothing like that of that on an actual new iPad. Test on actual hardware.

CATiledLayer generates a lot more tiles on the new iPad than on older devices, even when using the same settings. At the moment I detect whether the code is running on a hires screen (via CALayer's contentScale property), and if so, set a bigger tile size.

I'll be doing more experimentation, and will post any significant findings here.
