NVIDIA statement on Batman AA
A representative of AMD recently claimed that NVIDIA interfered with anti-aliasing (AA) support for Batman: Arkham Asylum on AMD cards. They also claimed that NVIDIA’s The Way It’s Meant to be Played Program prevents AMD from working with developers for those games.
Both of these claims are NOT true. Batman is based on Unreal Engine 3, which does not natively support anti-aliasing. We worked closely with Eidos to add AA and QA the feature on GeForce. Nothing prevented AMD from doing the same thing.
Games in The Way It’s Meant to be Played are not exclusive to NVIDIA. AMD can also contact developers and work with them.
We are proud of the work we do in The Way It’s Meant to be Played. We work hard to deliver kickass, game-changing features in PC games like PhysX, AA, and 3D Vision for games like Batman. If AMD wants to deliver innovation for PC games then we encourage them to roll up their sleeves and do the same.
