   Hey,

   Not sure if anyone will have any solutions to this, but figure I'll try it out anyway.

   So, I'd been debugging my game in the simulator... super fast fps obviously. On the device it was still running at 60fps though. Then, for some random reason, the framerate dropped to 40 fps.

   I'm running an iphone 3Gs.

   I mean, I can understand if I made changes to my code, but the only changes I made were to the Game Scene, not to the Menu scene which launches initially. The menu scene was running at 60fps, I made zero changes, and now it's running at 40fps.

   Is there any device specific thing I did to reduce the framerate?

   I've thought about it, and the only thing I can think of that I changed that might affect the menu would be adding breakpoints.

   any thoughts about anything that might be causing this? debug stuff? xcode stuff?

   thanks!

   thanks,
   w

   It is a known problem with the 3GS and will be fixed next month.

   In my game, I forgot to remove children of one kind of bullets that I used. They were invisible and untouchable so I just forgot about them. After shooting a couple dozens, the framerate dropped from 60 to 30 and after that, a couple dozen later, 20...10... etc.

   It was steady and wouldn't go higher afterwards.

   Maybe you have a couple unwanted children somewhere in there.

   Or, it might be the bug that Steve mentioned.

   Thanks Steve & Qcmat...

   I fixed the problem. Stupidly, all it took was a reboot of the iPhone. But in general, the drop seems to happen once and again, si thanks for the tip.

   Rebooting fixes the problem but it will return. See this thread:

   I know this is an old topic, but I'm just wondering: does anyone know of a way to track this issue or get any more information? OS 3.1 is out, but the problem persists, and the only mention I can find of this issue is various users calling it a "known problem" with iPhone 3GS on Cocos2d forums. Any ideas?

   Thanks!
