It's an updated Reshade DLL file, the config is exactly the same as the one currently on the repo, since this post I have updated the zip file on the repo to include the new dll file. Just replace d3d9.dll with the new one. It makes AA sharper and also has faster loading times in Performance mode.
I must ask this, but what setup was used for the most recent screenshots you've posted in the random screens subforum? Whatever it is, it's very crystal clear, and I know for a fact that it would look nice for the pictures I take.
