Hi folks,
Just for some added clarification, which multiplayer server you select only changes which other players you see in multiplayer mode. The multiplayer servers do not affect anything in the sim that might affect your performance* like data streaming, live weather, live real-world traffic, or any other online services. If you are experiencing degraded performance, it has nothing to do with changing multiplayer servers.
Thanks,
MSFS Team
*Except, perhaps, a very small performance hit if you’re now seeing more multiplayer aircraft around you because the East USA and Western Europe have more players than the retired West USA and North Europe servers.
