Is this game really that badly optimized or am I doing something wrong? I have never had a game run this bad ever, and that is saying something. When I'm in the wasteland I have playable frames (20-30) but when I go into the inner city like around diamond city my frames dip below levels I have never seen before. I will usually get 10 frames followed by 5-10 second feezes and then 1-2 frames in the city. It bothers me that there's a mission I'm on and I can't even do it because it's unplayable. I'm playing on the lowest possible settings in everything and I'm not running anything extra in the background. I even lowered my resolution on my 2560x1600 monitor to 1080p, but it doesn't do anything.
My specs are
CF HD 6970 2GB (even though I read CF doesn't work on Fallout 4)
Intel i5 4670k @ 4ghz
8gb of ram
Any advice on what I can do? I'm frustrated that I cannot even play more than half the content on this game which is something I can never say I've experienced before. I even ran Fallout 3 on the highest settings yesterday without the slightest hiccup.
