*Was said DX11 support witnessed at the same time as this purported Skyrim viewing? Skyrim already DX11 ready? If so, it would be fantastic if the PC version shipped with DX11 features and it could happen if they've already started. Hopefully this, at very least, means DX11 for Skyrim is pending.
*hopes it's true*
Also, I'll bet they've some monstrous PCs in their office.
I was passing through, I shamelessly showed them my CAC card showing I was USAF (mainly as a joke) and asked if they could give me a showing since I hardly saw any for PC. Since the game is designed on the PC, most of their systems were top of the line to handle the amount of rendering needed. It was just a room with a few comps (a few Xbox 360's not hooked up to anything but didn't see any PS3's), it was one of their viewing rooms. I was told DX11 support is in but I couldn't tell if what I saw was with the implementation. I thought it was but thinking back, he may have said it wasn't in the that beta demo. Regardless, it was breathtaking, reminded me of max quality in The Witcher 2 but with the Oblivion depth and quality. (Hard to explain better).

DX11 - That's probably what he meant
