Smart Delivery is the name Microsoft has given to a first- and third-party cross-buy and cross-save program between Xbox One and Xbox Series X. In short, it means that Xbox One games will be upgraded for free on the next-gen console.
Moreover, Microsoft has promised that Xbox One games will benefit from “steadier framerates, faster load times and improved resolution and visual fidelity,” without additional development work.
As currently experienced with digital downloads between Xbox One and Xbox One X, Xbox One and Xbox Series X consoles will download the appropriate assets needed to leverage the best from the hardware available.
First detailed on 25 February, Microsoft’s statement mirrors comments made to Stevivor by Phil Spencer back at London X019.
“Our goal for our first-party games is that your entitlements will be cross-generation and your Achievements will move effectively with your save game because that’s where they stand,” Spencer told us.
Moreover, since the February 2020 reveal, it’s been confirmed that third-party titles will also offer Smart Delivery capabilities. [Update: A full list of titles that support Smart Delivery (as of June 2020) is here.]
The Xbox Series X will be available in the holiday 2020 season.
