Since its release back in 2015, The Witcher 3 has received on PC a variety of mods which change the game’s lighting system. While some are impressive, like the Super Turbo Lighting mod, they bring some unwanted issues due to the excessive brightness of textures. From today, however, this issue will be no more.

Zupremo recently released the Reduced Texture Brightness mod, which adjusts the brightness of textures when a lighting mod and ReShade are used. The improvements are quite noticeable, so make sure to take a look at the mod if you want to experience The Witcher 3 like you never did before.
