Please do me a favor and go to the app store and check for app updates and please let me know if it stutters. It still stutters for me.I just went into my App Store, scrolled all the way down the main page then switched over to the account page, scrolled down, scrolled back up and hit "Install All" for the three updates that were available. Not a single stutter, hang or loss of frames.
So it may come as a shock but blues eyes, nor anybody else registered on this forum, can speak for everybody.
