Have you tried with the stable version of FBW after doing the NDU tweak?
Make sure to restart your Windows after applying the changes.
NDU stands for Network Diagnostic Usage. It basically monitors the network data usage.
Why is it related to MSFS?
Because in MSFS Data settings, you can see that thereâs a Data Consumption and Limitation feature. Somehow MSFS is using and connected to Windowsâ NDU to monitor the data consumption. As you already know that MSFS is constantly downloading data from the cloud during flights.
Why disabling NDU may make MSFS smoother and more fluid?
Because most probably thereâs a bug on Windowsâ NDU (e.g. memory leak or process leak) which affects MSFS performance.

Issue is not plane-related. I get it on every airliner, so that would not make sense.
I have rebooted system after disabling NDUâŠ
Have you tried with totally empty community folder? I have seen same kind of figures in main thread which was caused by one mod (Finnish ecoregions in this case but there might be other mods too causing same kind of issues)
its already mentioned âŠ
there was a conflict reported, starting ten years ago, where a specific network driver caused a possible conflict which results in a ânone paged poolâ mem-leak.
If users not see here strange high values, then I assume there is no need to try these

Of course I had. I had literally tried everything to fix it - thereâs video of issue I took more than a quarter of a year ago: MSFS | Performance Degradation Over Time - YouTube
Okay sorry for asking, I probably missed just that video in thousands of replies here.
Sorry, as i can see there have been loads of replies today while ive been at work. Are we saying the toolbar pushback is the cause of the frame rate degredation?

Not for everyone but for some, so it should be removed before making any assumptions about the ndu edit.

Hm, already made a flight from EKCH to LOWI, it seems that it was slightly better, but stutters as well at LOWI (in EKCH no stutters at all).
So i gonna try the tweak described in this thread,

You mean a Screenshot of my RAM Usage in the Task Manager?
Seeing as Microsoft makes both Windows and MSFS, I wonder if a mod could raise this to an appropriate Dev to get an actual answer on whether it is helpful and/or safe to do this?

So after around 45 mins of flying from BHX and now West of Paris, which is notoriously heavy around CDG, im still getting solid fps. At the weekend over the same area i was getting around 20-25. All ive done is remove the latest better pushback mod from the community folderâŠ

Microsoft didnât make the latest MSFS, they produced it. Asobo isnât owned by MS⊠although everything about it from the Game Pass release to the update schedule works exactly like a first party game.
