I've just created a simple prototype to test how cocos2d performs that and what I've found finally - at the fast speed image is blurring or maybe it's better to describe that cocos2d are NOT running 60fps.
This is a simple circle moving fast and camera action CCActionFollow used to watch it.

Test only on the real device.

And here is slow motion video of this game:

I have played such types of games(very fast) made with other engines like Corona and there were no such problem. Image was clear even at the high speed. But in cocos2d image is blurry and very unclear.
So, I think this is an cocos2d issue. Is anybody have experience with such? And maybe this can be fixed in some way?
