Microsoft's Xbox Game Pass head Ashley Speicher announced on stage today at E3 that "Fast Start" is coming to Xbox later this month in the Xbox One June update. It's as simple as it says -- it starts games up "twice as quickly!"
As a sort of bonus -- Division 1, ESO, and Fallout 4 (as previously stated) will be enhanced with Xbox One X and will be playable today by way of Xbox Game Pass. Microsoft also re-iterated that they're very happy with the Game Pass so far, and it's hard to believe that it's been a year.
