Unfortunately this is a waste of time for you guys as I cannot do either of the requested. The only thing I can give is a description of what happens, and that is everything changes shades when moving/panning around. Green grass and trees get noticeably darker when moving the camera. They go from normal brighter shade when not moving, darker shade when moving and back to normal when not moving again. I was thinking it was something that would be an obvious fix to a common problem, but that apparently isn't the case.
This isn't isolated to Arma 3 as I notice it in other games as well. The only difference is that it's much more significant in Arma 3.
So this thread can be deleted/closed.
