Hi,

I just finished one game and it works fine but having one problem with FTP. I am getting 38-42 FPS constantly but some times it goes down to 15-20 FPS for 2-3 seconds and return to normal fps. It doesn't have any problem on iPod Touch but i am getting this problem on iphone.

First i have developed game without sprite-sheet and there was no problem that time. then i used sprite-sheet in project and then after i am getting this problem. So did i missed something related to remove all the atlassprite or clean up atlasmanager.

Anyone has idea about this.

Rgds,
Iphone Dev.

Does it happen only when your phone is checking / retrieving your email in the background? I notice the same thing, always coincides with the phone grabbing my email. FPS drops in half (or less) for about 3 seconds. You might not know if though if you don't get any new email at the time because no "ding". Test it by emailing yourself them playing your game.

Hi Rig,

I used link director but even though it gives me slowdown problem. I used following code,

I have used following code,

if( ! [CCDirector setDirectorType:CCDirectorTypeDisplayLink] )
{
NSLogMy(@" === Link director");
[CCDirector setDirectorType:CCDirectorTypeDefault];
}

I tried many things like hashing, removing sprites, reduced sprite quality to 8-bit but still problem is there. Anyone have idea about this problem.

Maybe you're removing alot of AtlasSprites at runtime? Removing an AtlasSprite is supposed to be quite slow.... So try disabling the sprite by moving it off screen and reuse it later on if that's the case...

From the docs:

Warning:
Removing a child from an AtlasSpriteManager is very slow
