I've sucessfully flown with a few different people using the multiplayer feature. A couple nights ago I was trying to fly with a friend of mine. As soon as he entered the session his frame rates dropped from 30fps to 3-4 fps. If I stopped broadcasting my plane they jumped right back up. We had the same problem if I was the host or he was the host.
We are both on the same and latest version.
Both of our frame rates are locked in the sim at 30fps and they usually stay there.
As a test I we connected using a different multiplayer platform and had no drop in frames.
Any ideas on what may be causing the issue are most welcome.
Thanks in advance.
