== Description ==
If users prefer to play their game directly from disc, PS4 will install data to the hard drive during play.  
PlayGo (by using a [[CXD90025G|secondary custom chip]]) allows immediate start of [[Game_Titles|supported games]], with only the need of the first [[PLAYGO-CHUNK.DAT|chunk]] of game data. The following chunks are downloaded/installed independant of the [[APU|mainprocessor]] and relinked/copied when complete. Order of chunks can be rearranged as game progresses (e.g. user takes a different road in game, thus requiring different maps/data). There seem to be a maximum of 100 chunks, with no limit of size.


If users prefer to play their game directly from disc, PS4 will install data to the [[Harddrive|hard drive]] during play.
Similarly, system updates are downloaded seamlessly in the background without interruption.

PS4 also features technology that attempts to determine trends, including titles a gamer is likely to express interest in next, and then automatically download a small percentage of those games in the background, even in sleep mode.

Killzone: Shadow Fall supports the PS4's PlayGo functionality, allowing players get gaming before the whole game (39.7GB ) is downloaded, but it's been confirmed that this initial download is still a sizeable 7.5GB.
