Those of you expecting more whiz-bang effects over the console versions will be disappointed, however, as Assassin's Creed II is a DirectX 9 affair.
"We are using the same rendering engine as the Xbox 360 version which is based on DX9. Integrating DX11 in our renderer would have definitely been too much time-consuming given our release date," said Champagne. "Assassin's Creed II has no specific support for DX10 (but the game still runs smoothly on both DX10 and DX11 systems)."
While that piece of news is disappointing for gamers who have purchased a new ATI Radeon HD for DX11 hotness, Champagne cites a Steam survey that has 40 percent of gamers still using Windows XP.
So when will he feel the need to jump to the newer API? "I guess when most of the gamers will have switched to DX11.

According to Steam HW Survey, 40% of the gamers are still playing under Windows XP. I think we'll have to wait a bit..." he answered.
