I figured it out, sort of. It's weird though. Super-resolution acts differently than it did on windows 7. See, on windows 7 all I had to do was turn the feature on and then change the resolution in game.
For some reason on Windows10 I have to go into each game's "profile options" and change the Display Scaling option to "full panel". It's weird though! Because a lot of the time a game's opening screen, (you know where it shows company logo's). It's stretched out and it's not fitting but by the time I get to the games title screen, the scaling fixes itself and the super-resolution work perfectly.
AMD Control panel > Gaming > Fallout 4 > Profile Options > Display scaling=full panel
On Fallout 4's game options I chose 1440p super resolution for my 1080p monitor.
The first screen after you start the game may not scale but the next screen will. But now that I have started the game a couple times it's scaling properly right away. WEIRD
