DirectStorage API is now available to be shipped alongside games released on Windows. With it, developers and players will have access to best-in-class IO tech on both PC and console just as DirectX 12 Ultimate does with rendering tech. This translates into highly reduced loading times while providing more detailed and expansive game worlds.

The DirectStorage API is the response to evolving storage and IO landscape in PC gaming. DirectStorage will be supported on certain systems with NVMe drives and work to bring gaming experiences to the next level. This feature is now available to all Microsoft partners to ship with their games. The technology will also be presented during this year's GDC.
