Just wanted to say that you can use the Skyrim Crossfire profile for fallout 4.. it works flawless for me and gives me a nice speed bump. Their is currently no Fallout 4 Profile yet.
also some people are finding the game locked at 30fps.. their is a tweak to turn this off
.1: Unlock Frame Rate
Many PC gamers have discovered that Fallout 4 is locked at 30FPS for them. This is bizzare because for others it appears that Fallout 4 runs at locked 60FPS. To unlock Fallout 4 frame-rate or this 30FPS cap issue follow the steps provided below.
To unlock frame rate open Fallout4Pref.ini (simply search windows for it, but it is in your documents). Note making a backup isn't neccessary as if you simply delete Fallout4Pref.ini the game will auto generate new one next time it is opened.
Search for the line iPresentInterval=1, and change it to iPresentInterval=0
Next to use vsync got to the nvidia control panel or amd equivelant and apply vysnc here to avoid nasty screen tearing, as the above completely removes any frame rate cap.
Another possibly solution that may work for you is to play in a bordeless window mode
Also any ultrawide users here is a good site with some nice tweaks on how to get it up and going, playing a nice 2560x1080... shame i havn't slept and work is in 4 hours
