Kotaku: Installing Xbox One Games Takes Way Too Long

[freedquaker]

What I really believe what's happening is the following:

PS4 is not really installing the games initially, but rather copying the essential components of the game to launch the game. From that point on, they continue "caching" starting from the most frequently used components to the least. Then when you first load a campaign, it will be relatively slower since chances that not all of the parts were cached, forcing some parts to be read from the disc. The good thing is that this is really a well executed / streamlined process, and further loading will be faster as they'll be entirely cached.

On XB1, however, they are just basically installing the game; stage by stage. This is why it takes this much time. So the stages that are installed are instantly available, and load slightly faster than PS4 as XB1 reads the entire data from the hard drive unlike PS4 which reads parts of data from the Bray disc until the installation process is complete.On XB1, this is an afterthought. MS didn't originally plan such a feature, and they are merely trying to "response" to the streamlined process on PS4. Things may improve later though.
