title: Flex Tweening leads to high CPU usage
body: <p>I'm using TweenLite from greensock in a flex game. I have the requirement to perform some long animations where one object needs to go from x1 to x2 within hours. this is what im doing:</p>
  
  <pre><code>TweenLite.fromTo(obj, duration, {x:x1}, {x:x2});
  </code></pre>
  
  <p>When the animation starts immediately the cpu usage goes over 20% and remain this way untill the animation is over. since the animation could take a lot of time to complete i need something that doesnt affect the cpu usage so drastically.</p>
  
  <p>any idea?</p>
