   I have a parallax background scrolling repeatedly but then it's not smooth and kind of jerks. It's also running at 60fps. What are possible causes?

   Do you have other code? schedulers or anything that maybe printing nslogs to the console or otherwise causing slowdown for short bursts of time?

   No, my console isn't running any continous messages. But, my scrolling background uses the action CCRepeatForever.

   It actually may be running smoothly, but if other things on the screen are moving as well it may look choppy relative to their movements. You could test by creating a test scene where you only scroll the background and nothing else an see if it's smooth. This doesn't solve your issue but identifies whether it's the repeatforever or not.

   It still has the problem even if I only test the background scroll. I've also tried using 1024x1024, 1024x512, 1024x320,480x320, 512x256 and they were all doing the same thing.

   I just noticed that the parallax test demo that came with Cocos2d also have this problem. What's going on here.
