   Hey,

   first of all I want to say that this engine is really cool and lots of fun to work with, but I'm having a small Problem right now.
   I wanted to animate the Menu a little so that parts of the Menu slide in and to do this I used e.g. the following Code:

   [menu runAction:[CCMoveTo actionWithDuration:.4 position:ccp(winSize.width/2, winSize.height/2)]];

   I also do the same thing only with a different location for a couple of other Sprites.

   But my problem is, that without the Action I have constant 60FPS in the Menu, but as soon as I add the Actions (there are 4 of them) the FPS drops to about 30 and stays there even though the action is already done and they aren't moving anymore.

   So why do I still only have 30FPS although the Action is already done?

   Are you testing in the simulator or on a real device? The simulator is absolutely junk for performance testing, since it does not accurately reproduce the actual device.

   If your results are from a real device, I suspect something else is happening behind the scenes (excessive loads, loops that never resolve, etc.) that is not directly tied to the CCMoveTo command. The performance demands of a menu shouldn't really make a dent in FPS, let alone a permanent drop.

   Have you run your code through Instruments to check for leaks?

   @Creativ: You should show a bit of code because this behavior is strange. I use lots of actions and it's performing well in both simulator and device (iPhone 3G, last cocos2d version).

   I only tested it on the Simulator yet since I don't have an iOS Developer Account yet, but I will definetly test it as soon as I have my Developers Account.

   I also checked for memory leaks, but except one leak, that happens while preloading the sound, there aren't any. I think I read somewhere that the leak, that happens when preloading the sound, is a Bug from apple. Other than that there aren't any leaks.

   I'll let you know if I also have the problems with the real device.

   I just tested it on my iPhone and I don't have any performance-issues there.
   So the Simulator is only acting kind of weird.

   Thanks for your help anyways.
