Not a Clue here... been looking for an answer pretty much every where. If this were the Fallout 4 forums, I'd have had a 100 responses by now. I'm thinking that it's an in-game setting that I'm missing. I got the newest NVIDIA Drivers, used the Optimal Settings, no change. I'm at a loss. maybe something beyond our fixing.like you i'v tried to mess with the settings with no results.My driver is also up to date.Nvidia just gave one out the other day.it's like there's a fridge inside everyone's mouth and when the mouth opens it,s like the door has..lol
