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.
