This mod completely rebuilds pre-combined texture meshes and occlusion information for Fallout 4. 'Occlusion' refers to when an object blocks another object from being displayed. Fallout 4 has issues where objects, even when they're unable to be seen, are drawn. Fixing occlusion helps reduce draw calls, which, depending on location, should increase FPS.

On top of this, it also does two more things:

The Low End PC mod will boost every handheld far beyond what you ever thought it would, but will also reduce just about every setting in the game. Shadows are significantly reduced. The grass is completely disabled, with some plants still appearing. Depth of field, lens flare, SSAO, and god rays have all been completely disabled. Basically, this makes it so a potato can run it, almost literally.

BlurKiller - Visual Pollution Remover and Performance Enhancer

BlurKiller is a strong alternative for players who want more visual fidelity without resorting to the Low End mod. BlurKiller works wonders for combat when many of the game's default effects are increased. If players have a depth of field enabled, Fallout 4 will often increase this effect during combat, causing significant FPS spikes as a result. BlurKiller eliminates these changes and keeps the game at the default values in the player's settings.

Optimized Vanilla Textures - Full Version

As noted by the mod author, they noticed that some of the textures in vanilla Fallout 4 were not compressed properly, missing mipmaps, or other things. They fixed this by running them through a texture optimizer. While they can't promise results on every PC, it's worth a shot!
