I don't think we are talking about lag or bug code on here, more like the time it takes to do stuff because of the animation itself, I think they can speed them up somehow
Yeah not sure why they just Sony crank them up and be done with it. But they are supposedly already testing the GM internally. So who knows maybe it will be faster.
My first thought after going back to iOS 6 was. Damn the lock screen is ugly but man how fast everything runs. Everything in ios7 still has a slight lag.
