I've been working on a spritekit game lately and I'm really close to completing it. It's my first time using the library but I'm super excited to start getting the hang of it. I seem to be getting it just fine until I encountered my problem.

I was adding a background Image into my game and I got it to work just like this:

_background = [SKSpriteNode spriteNodeWithImageNamed:@"background"];
[_background setAnchorPoint:CGPointZero];
[self addChild:_background];

My frame rate was staying at a very high 60 FPS but as soon as I add the background image it dips all the way to a terrible 30 FPS how could this be. There is only 3 nodes on the screen. What did I do wrong?

I bet you are testing on the simulator ... – CodeSmile Aug 28 '14 at 00:08
Yes, iPhone Retina (4-inch 64-bit), Is there a problem with that? – Jacob Pickens Aug 28 '14 at 00:08
you put the background, 30 fps, comment the addChild method and run again, 60 fps? – Draelach Aug 28 '14 at 00:55
yep exactly. Dont know why – Jacob Pickens Aug 28 '14 at 01:01
You can read here : http://stackoverflow.com/questions/19556867/xcode-5-sprite-kit-examples-slow-simulator - Google "SpriteKit Framerate Simulator" and that's the #1 result. – prototypical Aug 28 '14 at 04:03
simulator is a software renderer – CodeSmile Aug 28 '14 at 08:11
