CrushBug says: "I suggest you play it and judge for yourself."
That's a very convenient thing for Bioware to say. Especially considering Bioware does not release demos for their games. Play (*pay*) the game and then make judgements.
Anyway, I've seen quite a few DA videos and screenshots. There's not a single one with trees having shadows. What is it? The eclipse engine can't render tree shadows? It looks weird - tall trees without shadows and next to them a few pillars with shadows.
