I am having some issues when trying to add a background image to my ipad game. The Image is a tile map that is made up of a 64 by 64 png (tried jpg too, no diff) This drops my frame rate from 60 to 30 as soon as I add this any ideas on what i could do this is how I am adding the image
background = [CCTMXTiledMap tiledMapWithTMXFile:@"background"];
[self addChild:background z:0];

I was worried about this too, but don't worry too much - you will get a significant frame rate increase when you get your app installed on the iPad device.
I managed to get something installed on a friend's iPad today which was running at around 8fps in the simulator with a full screen background sprite (1024x768), and around 30 100x100 px sprites (animated) bouncing around the screen using Box2D. Stuck it on the device, we get a respectable 45 fps.
A screen with just a full screen background image and a basic animated sprite (just a series of about 20 frames), get's a solid 60fps.
Hope this helps!

How is it Hacky? it's taking the optimum sizes that the system uses, just because you use 2 images to cover the background is not Hacky, it's printing 2 sprites instead of 1, in fact using 1 image could be classed as Hacky because you are too lazy to cut it into 2. I'm sorry I didn't make the system I just offered the proper way to do it for the hardware.
sorry if i insulted you or something, it wasn't my intention
im thinking about tile maps, i can make 1024x1024 (or even 2x size) map, draw it 2 times and it supposed to be faster then 2x sprites from separate images, but that's not what im observing on simulator...
Sorry if I gave that impression just a little stressed at the moment.
I'm not sure what you are saying about a tile map. I verified my findings on actual Hardware not the simulator, which you can not trust with speed, in fact it usually depends upon the machine you are developing on, in the simulator I can get different fps on my macbook and my imac with the same code.
