watch dogs has a vorpx profile “hidden”, so just start the game with the vorpx, and there is both the g3d that the z-normal … but the g3d has a flaw: at night, where there are artificial lights , there is an annoying effect of flickering, of continuous movement of textures..
If its a hidden profile, its probably not finished yet. Though sometimes turning OFF game-shadows can solve such problems. You also can check if the S3D shadow option on the vorpx image page is present, try changing that as well.
