Wanted to go check out the cliffs. I sure wish I could get sweet fx to work, but every time I try to load it up it fails when loading in the missions.
Have you tried reshade? - you can do some really good natural lighting, HDR, and color tweaks with it - it might work for you (if sweet fx doesn't (that was my situation - sweet fx doesn't work, but reshade does - though reshade is the more intensive tweak, go figure). Love the screenshots guys! some really great stuff!
