I have the same issue, but I also had this in the previous 10.4x version. I have multiple monitors, but one runs on the onboard adapter and the primary runs on a GTX980 that is in SLI mode. I seems to happen more often when I click out of xplane to the other screen. The problem is the timing is not always the same. But like you, I start 60-70fps and fail down to 2fps. I also notice that this failure messes up my Windows start menu making all the icons disappear. I have already tried uninstalling and performing a clean install of the latest video drivers but that also hasn't changed anything.
I hope there is someone more clever than I to help because at this point the simulator is unusable which is a shame since I am a xplane newbie that is really starting to like the direction the simulator is going. I have attached my log.txt file as I have since this is important.
That is because this "lag" is NOT an X-Plane issue. It is an issue with the recent Windows 10 KB3176938 update.
worked with NVDIA online chat support, they provided the following. Tried it and it did not help much.. i get best frame for a while (longer) with x-plane rendering Preset to low...
i share below the detail of the conversation if anyone can use.. and have more luck than me. Note: to date- silence from x-plane support. No one has even responded to my queries.
