Friday before last in a multiplayer flight we could all see each other no problem whether on beta or not... then last Friday it wasn't working at all.. everybody's FPS was way way down. unusable.. same multiplayer server we always use ( SE Asia )  but each week is a different part of the world.
If you spawned in away from other players, things seemed to be normal.  ( this happened to be in Oregon)

We previously found that people on 2024 beta could see those not on beta and vice versa.

The FPS going down when multiplayer is enabled is being discussed in this thread: https://forums.flightsimulator.com/t/what-have-they-done-now-ctds-mad-freezing-nav-screens-resetting-su1-beta-update-12-feb-steam-only/705166

If your FPS is going down when multiplayer is enabled in the SU1 beta, you may want to post in that thread, to help the MSFS developers figure out what the problem is.
