Graphics problem. (The Suffering)

Good day! Faced a problem bought the game and gog. I played normally for about a week. Then I decided to wish for screenshots, the overlay did not open. I decided to restore the game files. Since I put the crack and then the most interesting thing began, together with the default driver display - radion rx480, the game started to run through aticfx32.dll radio rx480, the texturing filter item also ceased to be active, there were problems with disappearing textures. I did everything I could: cleanly removed the video card driver, uninstalled and reinstalled the game and the gog launcher, but the game still starts with aticfx32, the problem with textures is solved by deleting dx105 in the game branch in the registry, but not permanently if the problem returns, the file is not created anew though it should. Aio patch doesn't allow me to use my saves, when you start with them, the game crashes after a few seconds of the intro. How can I fix the problem and return the original graphics driver? I just haven't reinstalled Windu yet.
