I have a big problem with my app.
I am few steps before the end of my app and today I wanted to add a background image.
My normal FPS is 180 during black background and when I added my background for iphone 4 sized 960/640 my FPS changed to 20-30 so its impossible to play. And next thing what happens is, when my player and enemy has a collision they stop their actions, but only if there is my background. I am using SpaceManager so maybe its because of its shapes. So does anyone know how to add background in another way in SpaceManager to do not slow my FPS? Here is the way I try to add Background:

-(id) init
{
CCSprite *background = [CCSprite spriteWithFile:@"Background.png"];

background.anchorPoint = ccp(0, 0);

[self addChild:background z:-1];
}

    the most likely cause for the drop in fps is because the picture is designed for the retina display, and since it is a large file it slows down the app. the device which you are using also has an effect on how fast the game works, so if its slow only on a 3gs or something like that just drop support for it.
