Black something instead of textures (The Witcher)

The problem appeared after installing the mod to increase the speed, to set modes on the quality of teksturki, with it everything worked well. Mostly black texture only drums and some items of furniture in homes, but go on, it happens that you walked into someone's house, salutala, came out, and you have the size of the earth disappeared, going as if on the black carpet. Anyone also encountered this mess?
