I don't know why but after updating to malwarebytes 3 fallout 4 has started to stutter badly.
Even at unlocked fps running at over 100 fps there is a stutter. It makes the game unplayable.
I know that some have trouble with this problem in general but I never have. It only started after the update!
At first i thought I was going mad, but then I found I was not the only one having this problem.
Malwarebytes Premium 3.0 causes stuttering in games
Only turning Malwarebytes off fixes the problem and I don't want to do that.
So in the words of the sinking man, Help!
