Digital Foundry have taken a look at fixed version of Fallout 4’s Far Habor DLC and have discovered the frame rate is now practically locked to 30fps. However, rather than improve the engine it looks like Bethesda have removed some of the fog and forest elements to speed up the game.
The only way to get the fix is to re-download the entire DLC, details of how to do that can be found here.
