PS4 is the latest model and is really with me whisper. You can hear the little / not at all, neither the menu nor in the game, even after several hours. I do not know where these stark differences come, but a little tip: The Ps4 needs have little air to breathe;)
Far Cry 4 is simply a great game and looks fantastic & runs smoothly.
Who took part 3 well will also love part 4.
