I didn’t have a flight running. No MSFS downloads were taking place at the time of the download test. I just had msfs running. This problem has been persistent for months. I’ve done a good bit of troubleshooting and am convinced the MSFS is somehow slowing all data transfers, in game and out of game, to and from my PC.
I recently uninstalled MSFS and reinstalled. The problem persists.
Also, my son also has and plays MSFS on his PC behind the same internet connection. He does not have download problems. He regularly gets 300 to 400 mbps speeds.
