After turning on the PS4 and accessing your account, use the D-pad or left thumbstick to navigate to the game you’re interested in updating. With the game you want to update still selected, press the options button on your controller.  Scroll down to the “check for update” option in the menu that pops up. If there is an update available, you’ll get a notification that reads, “An update file for this application is available.”  You’ll then be prompted to go to the downloads screen.  Press “X” on the controller to access the screen. If the game doesn’t need an update, the PS4 will let you know. At the downloads screen, you’ll see a full list of all updates available for your apps and games.  Select the game you want to update by pressing “X” on the controller, then confirm your decision to update the game.  Updates take time.  The amount of time they take to install depends upon the size of the update file. You can play games while the update installs.
