Testing of an early technical alpha of Microsoft Flight Simulator 2024 has revealed that the game's streaming data demands can reach as high as 180 Mb/s while in flight—a number that places peak utilization somewhere around 81GB per hour of gameplay at high LOD settings flying over densely populated areas.
Microsoft Flight Simulator 2024 has already caused some controversy due to its highly recommended specifications, but it's been noted that it has a much lower base install size than Flight Simulator 2020, at about 30 GB instead of the 130-400 GB required for Flight Simulator 2020 (higher range including DLC).
Meanwhile, scattered reports of MS Flight Sim 2020's bandwidth consumption point toward a more conservative ~100 Mb/s in densely populated photogrammetry areas, such as major cities. Usage in lighter areas could dip as low as 10 Mb/s, though the official Microsoft bandwidth recommendation for that game was 50 Mb/s.
