Since I don't have iPhone 4 I was testing my hi res images on my 3GS to see if positioning and images still looked the same by forcing [director setContentScaleFactor:2]. I noticed that any scene in my game run about 30-40 FPS even just at a static menu selection screen in either debug or release mode. The weird thing that I found is that if I set the preprocessor macro from COCOS2D_DEBUG=1 to COCOS2D_DEBUG=2 then the FPS now runs at 60. I even tried it with the test project hi res in cocos2D project and same result. Can anybody tell me why this is occurring maybe @riq might know.
Thanks
