Bit Tech has just published some news regarding the removal of DirectX 10.1 from Assassin's Creed, in which they talk with AMD, Nvidia and Ubisoft.
"I spoke to Richard Huddy, AMD's head of developer relations, on Friday in an attempt to find out when we can expect to see the path implemented again, because I'm sure that owners of Radeon HD 3000-series graphics cards aren't too happy that they're missing out on a 20 percent performance increase (when AA is enabled). Huddy said that he is working hard with his team to get DirectX 10.1 support back into the title for Radeon HD 3000 graphics card owners.
I pressed this point further on Saturday during a call with Nvidia spokesperson Ken Brown, and asked him if Nvidia had requested for DirectX 10.1 content to be removed from the game. "We aren't in the business of stifling innovation - it's ludicrous to assume otherwise. Remember that we were the first to bring DirectX 10 hardware to the market and we invested hundreds of millions of dollars on tools, engineers and support for developers in order to get DirectX 10 games out as quickly as possible," said Brown.
That response was to the point, but I felt it was worth pushing from another angle. I asked him if Nvidia ever signs exclusive deals with developers. "Every developer we've worked with on TWIMTBP has not been part of an exclusive arrangement - we do not prevent any developer from working with other hardware vendors," responded Brown. "Assassin's Creed is a great example of this because both Nvidia and ATI developer relations teams worked with Ubisoft to help during the development phase."
