Same exact thing, it is most likely CPU related... Mine is a AMD 1090T... which is also Phenom II.... did they poorly implement AVX2? I can be outside of main towns, like at my housing location... but when I go into town I get this problem also. I tried reinstalling drivers, reinstalling game... even did directx runtimes lol. I think this is more than a coincidence. If AVX2 is implemented for some parts of the game, can SE please confirm this? If so... possibly remove them until they are actually utilized?
