Microsoft has released two videos showcasing how Quick Resume works as well as the loading times that we can expect with the Xbox Series X.
Quick Resume allows you to go between multiple games and load straight into their suspend state. The demo shows several Xbox One games including Forza Motorsport 7, State of Decay 2, Ori, Hellblade and more.
The official wording is that this feature will work with at least three Xbox Series X games.
The loading times video also uses Xbox One games to demo, but shows hugely increased loading times (of up to 20-30 second improvements loading into a game).
This isbecause of the brand new NVME SSD that the Xbox Series X uses. It’s unclear how this will diff with Xbox Series X games, but there should be a fairly decent improvement.
