@Crunchmeister71 are you enabling MP when trying this? If so what about disabling MP entirely?
I’m making this suggestion for this reason:
ATC Callsigns missing - Bugs & Issues / ATC & NAVAIDs - Microsoft Flight Simulator Forums
NB: the first time I’ve tried WU4 near/over Paris it was a stutter fest impossible to use in VR at all. The day after same area, same conditions, not as bad as the day before. However, I’ve noticed name plates in MP where nearly all showing a number suffix to the name, like #248, and this might be related to the bug documented above in the ATC window (same type of bug).
