Today, Nixxes and Insomniac have announced the official PC specifications of Ratchet & Clank: Rift Apart. In a post that has now been taken down, they also confirmed that this will be the first DirectStorage 1.2 game with support for GPU decompression.
Senior Lead Programmer Richard van der Laan said:
DirectStorage ensures quick loading times and GPU decompression is used at high graphics settings to stream assets in the background while playing.

The SSD is screamingly fast. It allows us to build worlds and project players from one place to another in near instantaneous speeds. It is an unbelievable game-changer in terms of we can now do gameplay where
