Could be that importing screwed something, but the framerate stutter is there even on a new save. They screwed something up with the localized build.
Ahhh I saw this one Link. We will have to see though I am sure some of these reviewers would have run into sub 15 frame rates and commented on it.
This info about the frame rates means I'm not buying day 1. Even if it's overblown and exaggerated, I want more retail level impressions. Game is a lot of fun, but shitty lag fests are absolutely inexcusable in this day and age.
Never a bad plan to avoid games if you aren't sure of the performance plus the preorder stuff isn't that amazing since you can't get all of them unless you preorder on PSN.
