When i set my ATOC to anything other than disabled it causes graphical problems. If its set to grass, the grass will appear whitish blue and "Staticy". (As in tv static) Same if set to trees, producing same effect on trees.
If requested, i can record a video. I noticed this wasn't in known issues list, so would be interested to see if its a problem with the engine, or something my end.
