There are a few reasons why your PS4 might be slow and laggy. One reason is that the console is using its own processor to handle the game and graphics. This can cause the system to take a long time to start up, or even to crash. Another reason is that the console is using its own storage space to hold your games and other files. This can also cause the system to be slow when trying to load new games or updates. Finally, your PS4 might be having trouble keeping up with the demands of gaming. This can cause it to become very sluggish and difficult to move around in the game world.
