Assassin’s Creed Lead Programmer David Champagne has stated in a recent interview with PCGameshardware that the upcoming PC release of Assassin’s Creed 2 will be a DirectX 9 game.
While the game will run happily in DX 10 and DX 11, it will essentially be limited to the DX 9 feature set.
Furthermore, the game will not support Nvidia’s PhysX technology.
At this point, the game is looking like a straightforward console port, with no indication that it will implement any PC specific tweaks. Higher resolutions and increased multi-sampling have been confirmed however.
Champagne stated that they just don’t see the point embracing the advantages of DX 10 or DX 11 until more users have moved over to the technology. Unfortunately, if all developers maintained this attitude then there would be no reason for users to adopt new hardware standards, and the industry would cease to advance.
