Thanks for clearing this up!
The Unreal Engine 3 is must be very capable if it can get great results just by adding some routines, features, etc..
There is a point to my asking. It seems I'll need a new video card then if I want to see visuals like in the demo. I think this will require a high end Southern Islands or Kepler class video card.
If this was a brand new engine using future APIs, then it may require a DX12 card (even though it was demoed on 3 DX11 cards)
