PC fans are in for a treat next week as Bethesda plans to release a high-res texture pack as part of a larger update for Fallout 4. But be warned, you'll need a pretty beastly machine to make proper use of the upcoming High-Resolution Texture Pack. The update will also brings PS4 Pro features to the game including a resolution and draw distance bump (1440p and presumably, more trees), and "enhanced Godray effects".
In relation to the PC texture pack, you'll need an additional 58GB of storage to house those detailed Power Armor rust marks in addition to an 'Intel Core i7-5820K and GTX 1080 8GB' to ensure stable performance. Well, stable Bethesda game performance.
The update will also bring unspecified features to Mod content that will be detailed next week.
