Hi all, So I picked up an iPad 2 at launch but never bothered to get all the Angry Bird games in HD (I had the original on iPhone and that was enough). I finally decided to pony up the cash for Angry Birds HD, Rio HD, and Seasons HD. Rio and Seasons run perfectly fine. Smooth as butter, no frame rate issues to speak of - great games! However, the original Angry Birds HD, while not crashing or having "major" performance issues, seems to have a bit of choppiness in the frame rate. While in Rio and Seasons the birds, slingshot, backgrounds are all perfectly smooth, there is mildly noticeable 'lag' if you will on the original one. It doesn't effect the game play really, it's just weird that it would have choppy frame rate when it's sister games (and any other game on the iPad) doesn't. I tried a re-install of the game but it didn't really help. Perhaps it's just a bug in the newest version... I was just curious if anyone else noticed this. Thanks.
