Microsoft Flight Simulator Online Data & Offline Mode Questions & Answers

MSFS relies heavily on streamed scenery, photogrammetry, live weather and other online services, so data use and connection errors can affect both image quality and whether the simulator starts as expected. This hub explains what consumes bandwidth in MSFS 2020 and 2024, how to measure or limit it, and when rolling cache, manual cache and lower online-data settings help.

It also covers the common ‘You are currently offline’ message, sign-in and Xbox service checks, server outages, firewall or network problems, and the practical limits of offline mode. Answers are written and tested by the Fly Away team, including steps for preparing an installation before disconnecting and restoring online functionality without unnecessarily reinstalling the entire simulator.
