Game runs faster when launched by xcode...Why?

[macbeasty]

Hi Everyone,

I'm new to this forum. I have been making a OpenGl ES game which is near completion. However, I have one concern. I am part of the iphone development program and I have provisioned my ipod touch for development. Whenever I click build and run on my device (in release mode), it boots up my application on the ipod and I get about 59 fps.

However, when I disconnect my ipod touch from the cable and simply click the icon of the game installed on my ipod touch by xcode (it only gets 48 fps). So basically, when I launch my application through xcode (not using simulator), my app runs faster than when I just click the icon for the game independent of xcode. Why is my app running so fast with xcode or so slow without it? How can I fix it?

Thanks,
Nick
