Unlike the current "Ready to Start" system, which is manually configured during development, FastStart uses machine learning based on how gamers actually play each game. What's more, as an Xbox platform-level feature, developers will not be required to do any extra work for their titles to experience the benefits of FastStart. While FastStart does not speed up download times, by identifying which files are needed to begin gameplay and prioritizing the download of those files first, you can expect to jump into your game, on average, twice as fast as you did previously.
That means if a game previously took 30 minutes to download and play, you will now be able to begin gameplay after just 15 minutes. In addition, since FastStart takes advantage of machine learning, we will continue to improve our algorithm over time getting players into the fun as soon as possible.
Games will still download based on your local bandwidth, and you'll need to have an internet connection with at least a 20Mbps download speed to take advantage of FastStart. That minimum speed helps maximize the number of users who can take advantage of FastStart while minimizing the possibility of experiencing gameplay interruptions.
