Microsoft Flight Simulator 2024 sucks up to 180 Mb/s of internet bandwidth while in flight — peak rate equivalent to 81GB of data per hour. At least that install size is light, right?https://www.tomshardware.com/video-games/pc-gaming/microsoft-flight-simulator-2024-sucks-up-to-180-mb-s-of-internet-bandwidth-while-in-flight-equivalent-to-81gb-of-data-per-hour
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.
Of course, we should wait for the game's final release before dooming and glooming too hard about the outlook here. But gamers who have to work around strict data caps should be wary of Flight Simulator, especially the 2024 rendition, if what we've been seeing so far is any indication.
And this is almost certainly streamed to local disk. That could put a signifiant write strain on your SSD, unlike the write-once pattern that normal Steam games have.
