Weird thing keeps happening about once ever three days: In the advanced tab of my graphics, the graphic API section will change from DirectX 11 to DirectX 9 by itself; which is a huge FPS hit if I don't notice the change. So before I log in (having gotten used to it happening), I check the options because you have to restart game if you have to change it back. It's not a huge deal, just more of a pain-in-butt type of thing.
Anyway, anyone else have or had this problem? Or any possible solutions on how to fix it from auto changing on me once or twice a week?
