Update:- I have found something that has to be added to the existing code. The SWF embedded here runs only @ around 60 FPS on a Safari or Firefox on a Mac. I will work on a more consistent render loop code adding some timer calculation elements soon.
I have ported the Tile based scrolling in Flash code by Andre Michelle to use Actionscript 3.0
Main challenge I faced was the tearing issue which was removed after I used Timer Event and updateAfterEvent() method. Thanks to 8bitRocket site for the tip.
I am getting a blazing 160 FPS in browser.. OMG Flash rocks ! If anyone wants me to provide comments and documentation for the code. I will happily do it on request.

P.S. If its slow, its because you might be having the static noise swf playing below (scroll page down). View on the post page by click the title to ensure it plays smoothly.
