If you are a fan of The Witcher 3 HD Reworked Project by Halk Hogan PL you might also be interested in the version created for Fallout 4.
What the HD Reworked Project does is change the look of many objects from drab to a higher quality, without hurting performance.
If you watch the video, you will see barrels, trees, road cones, and other random environment objects are more detailed and vibrant when applied.
Hogan notes that static barrels and tires outside areas with workshops haven't been changed due to having separate models. It sounds as though this could be rectified in future updates.
There are two versions on offer, so those who have "weaker hardware" may wish to download the performance version which offers less of a performance cost. However, if you are running the game with a decent system, you shouldn't have any issues.
Have a look at the Fallout 4 HD Reworked Project from Halk Hogan PL over on Nexus Mods.
The most recent Fallout 4 patch, version 1.4, is now out of beta and live on Steam. It supports the upcoming DLC packs, the first of which is slated for March. The update also adds new settlement crafting items and the usual bug squashing which occurs with patches.
