This update adds the following...
Restored a missing texture from the Central Libya terrain and you should now see smoother pebble like rocks appear in concave erosion channels where water is likely to have flowed.
Added a "Visibility" option to the weather which will adjust the global fog on a map. This doesn't currently effect A.I. visual ranges but it will do at some point as well as effecting laser designator ranges and id ranges.
Updated the shader used on the burning smoke columns so that it fades into clouds correctly. Most noticeable when the clouds are set to "Foggy"
Extended grass draw distance to 5km in the Video Options menu. This can cause noticeable slow down.
Tweaked the tessellation & parallax settings to draw slightly further away from the camera to reduce shimmer as the effects become visible.
Adjusted the mission start times so that "Dawn" is now just as the sun is rising and "Evening" is near sunset.
Added some extra foggy weather presets
