I have a similar problem as OP. As it turns out to be ini tweaking broke something: always low res textures even though the video memory uses 1.7-1.8 gb of 2 gb of ram. Deleting the ini and let FO4 make new one fixed it for me.
I didn't enjoy it so far. Too much QTE, cutsence, and loading screen. Died a zillion times because of the clunky QTEs! :down: Wonder why Capcom didn't meet their sales figure. :blink:
