I have disabled all addons, deleted the WTF, Cache and interface folder.
I have also dropped video settings when it happens to low and also have tried DX9 and dx11.
Nothing seems to affect it.. and this is the only place I get such a weird FPS drop. I have played to 85 before and everything runs flawlessly at 60fps on high settings.
It doesn't even feel like a normal FPS drop, it starts to affect my game play and is very sluggish.
Org drops my fps to 30-40 in certain areas but this definitely feels different.
