Bit more Z-fighting where tree intersects with mountain terrain - Example screenshot
Most clouds are still quite fast moving, fine for just watching but might get distracting for gameplay
CPU levels dropped from 90-95% down to 15-20% on i5-2500k (base clocked)
Memory levels nice and low still - added less than 200MB of ram use
Graphics levels ~30% during windowed mode (75% of screen) upto ~55% full screen, down from 80-90% on windowed mode on test 1 - AMD 7850
Otherwise running nice and stable
