" In fact, generally speaking, performance remains smoother in both PS2 and PSP versions of the game. We still have elements in the game remaining from the PS2 generation and the gold standard 60fps update clearly hasn't been met with the consistency we would have liked."
Oh dear. Not the inconsistency 60 FPS part, but using elements from the PS2 when the PS4 is already available is just crazy. I can't believe Sony even allowed this for a franchise that used to be that big.
frame rate dropping to 30 frame is not acceptable
