The mod named Magical Graphics Settings introduces “Magical” settings that enable Witcher 3 to go beyond the vanilla Ultra settings.
The creator of the mod has said that the Magical Graphics Settings have undergone extensive personal testing to the point of “you better get off the computer or we’re getting a divorce” to make sure it doesn’t impact stability, unlike other mods.
Here’s some comparison images courtesy Mod Creator:
Mod stability and code cleanliness are paramount. I have in-game tested these values to a “you better get off the computer or we’re getting a divorce” type of commitment. Please understand the intent of this mod is to go a setting above Ultra, not to change the entire look of the game. I want to give a proportionally visual and performance effect like going from Medium to High or High to Ultra presets.
It can be downloaded over on Nexus Mods here.
The Witcher 3 is receiving a next-gen upgrade this year for the PC, PS5 and Xbox Series X/S.
