High scenes are fine but the vis range is important here...on high setting I get stutter and lower fps generally especially when tgp and other sensors are used.So I use modified med vis range with structures set to high setting which shows bridges,power stations and pylons etc further out breaking up the green blandness a bit.
On the preload,60k is fine for me but depends what vid-mem you have.:thumbup:
I dont think much more can be done with this graphics engine...the overall flatness and lack of terrain bump mapping being one of the worst features of it...we wait in hope for EDGE.
