I wrote a gaming application for iphone 4.0 and it's working fine there, and t开发者_开发百科he same application showing low frame rate with Iphone 3GS having IOS 4.2.

I did google and some forums said that core animation is slower and they suggest to use OpenGL ES, after that I ported my application for OpenGL ES and guess, it was worst than core animation.

What might be the issue any suggestions ?

You can get more information on your problem by running the OpenGL ES Analyzer profiling tool in XCode. There's a really good video on these tools in the 2010 WWDC videos - session 419, I think.
