Not sure how long the link pointed to by this Boing Boing post about Unreal 3's amazing detail will last. Let me know if it dies, I have a copy :) All I can say is "wow" and "wish the video was high res". Unreal 3 will kick ass visually, it looks like Doom3 on steroids. They are showint it off only because of the new nvidia card, which is the first card (at $900CND approx) that can handle the engine. However, the millions of polygons and all realtime lighting and detail are no doubt worth it, and we'll all be upgrading in a year or three when Unreal 3 is released. Just wish Doom3 would hurry up and arrive :)
This is where the link goes.
