I run LNM on a second monitor and everything worked well 😉 but since the latest update i seem to get pauses in the sim for a couple of seconds.These pauses are intermittent and seem for no reason.The same thing happens with XP11 and MSFS2020.If i run LNM on my laptop using NavConnect i have no problems.I tried all manner of other tests to find what was the cause until i stopped using or moved LNM to my laptop.

Hope someone can help so i can get back to my original setup

Thanks

I have gone back too 2614 from 2615 and all is well again 🙂

Strange. Nothing has changed in the simulator connection between 2.6.14 and .15.
What you can always try to narrow down the issue:
Disable weather downloads.
Limit map details.
Reduce map updates in LNM (i.e. use a bigger bounding box for aircraft updates).

BTW: Maybe a Windows update dropped in? I had some issues with stutters in X-Plane after Windows forced one of its "updates" on me.
