A free mod for Witcher 3, by Drogean.
The Hidden TextureMipBias Options Slider mod adds a new sliver of options to the hidden TextureMipBias setting introduced in patch 1.04 of The Witcher 3: Wild Hunt. This slider allows you to tweak that effect on the fly, without having to exit the game. It is especially useful for those who use Android and find that their phone's processor is weaker than what is required for the game to run properly. In that case, it is better to lower the settings of the game to the minimum, which is what this slider allows you to do.
The most important change in this slider is that it adds a new option to the hidden TextureMipBias setting. You should now have a new slider under Options > Video > Graphics that says "Sharpening" under the Texture setting.
