This is meaningless. Dx10.1 is just another gimmick to confuse people. Nvidia already have one pointless gimmick (physx), do they really need to get onboard ATI's share of this crap too? It's not like you can notice any difference in Assassin's Creed dx10.1, back when it's still supported. Far Cry 2 is just an underwhelming console port no matter how many gimmicks they try to load it up with.
