Bethesda has posted a new website entry on Fallout 4 giving you a short lesson on the graphics technology behind the game.
According to the developer, the first thing it did after Skyrim released was enhance the Creation Engine’s graphical core by "adding a physically based deferred renderer."
This new renderer allowed the team to add more dynamic lighting to every scene as well as "paint surfaces with realistic materials."
"We want objects and characters in the world to feel tactile and grounded, and a big part of that is ensuring that these materials are distinct – that metal reflects light in a distinct manner from wood, for example," reads the post.
To create the fully dynamic time of day and weather, the team worked with Nvidia on the volumetric light spilling across the scene.
It was also noted in the post that the "material system allows the surfaces" of the world to get wet, and a new cloth simulation system was added in order to make cloth, hair, and vegetation blow in the wind.
The post also goes into dynamic post-process techniques which "enhance the vibrancy and color"; how the virtual cameras received a major upgrade and it provides a list of additions made to the Creation Engine.

Fallout 4 is out November 10, which is just around the corner.
