There are a few reasons why games on the PlayStation 4 can take a while to download. One reason is that Sony has implemented a system called “patches.” This system allows developers to release new updates for their games automatically, without having to go through the hassle of releasing them through official channels. When a new patch is released, Sony will automatically install it on all PlayStation 4 systems. This means that if you’re waiting for a game to download, it may take some time. Another reason why games can take a while to download is because of the way that PlayStation 4 works. The console uses an algorithm called “progressive scan” which means that each frame of video is stored in memory for a certain amount of time before it’s played back. This means that when you try to play a game that’s been downloaded recently, your computer may have already played it and you may not even realize it because the game has been stored in memory for a while!
