title: cocos2D frame rate is only 30, without any actions?
body: <p>I have this in my app delegate: <code>[director setAnimationInterval:1.0/60];</code></p>
  
  <p>Despite this my app is running around 30 fps. What is weird is that it is currently doing absolutely nothing. the <code>init</code> for my only layer does nothing more than add 6 sprites based on images, and no actions or running, they are merely displaying on the screen. The total size of these sprites is around 500 KB total. In simulator or on device the FPS displays around 30.</p>
  
  <p>What could cause such a low frame rate when nothing else is going on in the app at all? There are no scheduled updates and nothing running at all; just displayed sprites.</p>
