Ubisoft confirmed that the decision to remove DirectX 10.1 support was made by the game developers and expressly denied any external influence. Michael Beadle, a senior PR manager at Ubisoft, admitted that there was some co-marketing between Nvidia and Ubisoft, but he said that "had nothing to do with the development team or with Assassin's Creed."

Nvidia, on the other hand, denied any financial agreement "Nvidia never paid for and will not pay for anything with Ubi. That is a completely false claim," said Derek Perez, Nvidia's director of public relations. In the past, during our talks with Nvidia's Developer Relations Team, the company has pointed out that Nvidia spends a lot of money sending its own engineers to development studios to help support them - whether or not that is what Beadle is referring to is unclear
