A powerful developer would have made the game run at 60fps.
Of course the PS4 isn't powerful enough. Nor XBO or Wii U or NX or Neo or anything. No console will ever be powerful enough for these guys because console devs always want to get into a dick-measuring contest with PC. A contest they can't win without cheating AKA making their games run at a sub-par framerate of 30fps.
EDIT: Let me just clarify - of course the PS4 is powerful enough, but I don't like that developers are placing unattainable expectations on it and making their game run objectively worse to cheat those expectations.
