Shadow Boost is the plugin for Fallout 4 that adds an ability to dynamically control shadow draw distance depending on desired user defined fps.
Users have noticed that in some locations of Fallout 4 fps gets low even with a good hardware, mostly it happens in the areas with lots of objects, this plugin is aimed to change that.
1. Copy ShadowBoost.asi and ShadowBoost.ini to the game's main folder, i.e. where Fallout4.exe is located.
2. In order to load asi plugins you need to have asi loader installed, so copy Fallout 4 asi loader (xinput1_3.dll) from this ditrib to the main game folder as well.
Since the game isn't properly optimized, almost everything that it does with objects which it renders takes more time than it actually should. One of the most time consuming operations in Fallout 4 is shadow rendering and because the game has only predefined shadow draw distance, which applies everywhere in every location just the same, we have a choise either we set it to high value with having a good picture but eventually facing fps drops in locations with lots of object or we lower the value to make fps more stable in general. And this is exactly the point where this plugin comes handy!
