Engine: Cocos2D
Test Hardware:iPhone 4
SDK:3.2.5 final

FPS is stable on 60 in DEBUG & RELEASE mode when we test our game in SIMULATOR. When change our test method from SIMULATOR to DEVICE, a real iPhone 4, game shows no low FPS under DEBUG mode. BUT things go crazy when change to RELEASE mode. FPS goes extremely lower than all situations I describe before. FPS sharply drops from 60 to 20~30.

Don’t confuse, in one sentence:FPS drops sharply from 60 to 30 around in RELEASE mode based on real iPhone 4 test.

Any one has any idea on how to handle this? Thanks for all kinds of aids.

    The obvious answer is to check the differences between your debug and release build settings. Thumb code generation comes to mind, don’t know if that still applies.
