The Xbox Series X and S will make it possible to jump quickly between different games with the Quick Resume feature. A new video that has been shared online recently shows exactly how quickly this will happen on the Series S.

The video, which has been shared on the Series X/S subreddit, highlights how it will take very few seconds to load from one game to another. The video only shows Xbox One games, sadly, so we do not know if the process will be as quick for next-generation games.
