It just started taking a Very long time to load and the frame rates dropped from 40+ down to3.  I don't know what changed?

Win10 updates in progress?

What does task manager have to say about it.

When that happened to me it turned out to be a piece of freeware scenery.  Whilst cityscapes made from Google earth images might be be wonderful visually, they certainly tax your system heavily unless they are very well optimised.

Most of them are not optimized in poly counts and this destroys frames needlessly.

I turn off sceneries which I don´t use using the msfs addon linker. Very easy turn them on if I fly to those places where I need them. Excellent piece of software.

maybe   a mod is the culprit?
