Actually, I do get good transparent buildings and everything else looks good except the smoke, plus the explosions are fairly weak.
I get really outstanding graphics when running my flight sims (Janes WWII fighters, Enemy Engaged) and even (should I say this here?) Unreal Tournament. I don't see why the graphics in this game should be any worse than those others, as they are much more system taxing.
Otherwise, outstanding game BTS!!!!!
