Being introduced as a way to combat massive game installs and to avoid crippling Xbox One users, Microsoft is rolling out a feature to Xbox One and the Xbox One X that's actually pretty clever.
Unveiled by Digital Foundry overnight, the feature is called Intelligent Delivery. It's basically a way for developers to segment a game's data into "chunks".
From a user perspective, files like audio commentaries can be managed through the Xbox dashboard - and deleted if you don't need them any more. From a dev perspective, it means XBO/XBS users don't have to download 4K assets - because that can be assigned as a chunk just for the Xbox One X.
It should also mean that you don't need to download bits of a game that you don't need, reducing download times. The whole breakdown is below, but it's a pretty reasonable idea given how enormous game installs are getting.
DF cites FIFA, with lots of different audio tracks that players don't need, but another game that comes to mind is Halo. What if you don't want the next Halo campaign? Or what if you only want single-player?
It'll be fun to see what devs can do with this feature in a year or two's time.
