Guild Wars 2

I have a 1080TI all updated and all windows updates, every game works perfect over 100 plus FPS but for some reason Guild Wars after this last patch lags to no end….. Is anyone else having this problem? What can I do? I have never had this problem until 3 or 4 days ago and now I cant even play passed 11 FPS anymore. I even lowered my settings to the lowest you can get and its still getting 2-3… What the heck is happening and is this poor optimization on their end?

Seems to be a problem with the Windows patch.
I had exactly the same problem and had to revert to the previous version of Windows which fixed the problem.
There are some suggestions that the Windows patch replaces the custom video driver with a generic windows driver which is slower.
