Hail, I noticed that activating "extreme graphics" doesn't actually maximise each and every setting and it doesn't turn everything on after switching from default to extreme. For example, after activating extreme graphics, you still have to activate sun shafts, ambient occlusion and a few other sliders to "very high" or "very far" details. In addition, when playing in windowed mode, the graphics look a bit downgraded and the colors actually look washed out, but switching to fullscreen actually increases graphical fidelity and colors. I therefor suggest changing extreme graphics to actually push everything to its very max. Cheers
