MOD author Painstaking Rick has released a new 4K Material Pack for Fallout 4, with a capacity of about 41GB, optimized for all materials in the game. The total number of materials optimized is as high as 40,962.
This MOD strives to make the optimized 4K material run close to the original material. That said, if your computer can run the native version at 60fps, there will be no change in speed after installing this 4K mod.
Interested players can do so with this mod.
The author also published screenshots of the comparison between the MOD version and the original version (each group of pictures above is the original):
