CATransition slow and picture jump when do transition on a large size picture
<p>I used CATransition to do transition between two images. But I found that if the image file size is large, the transition will be slow or jump.</p>

<p>Especially on case:</p>

<pre><code>type:kCATransitionMoveIn, kCATransitionPush, kCATransitionReveal, 
subtypes:kCATransitionFromLeft, kCATransitionFromRight, kCATransitionFromTop, kCATransitionFromBottom
</code></pre>

<p>Is there anyone met the same problem?</p>

<p>any comments?</p>
