Batman Arkham City
Batman Arkham City was developed with a recent version of Unreal Engine 3 which supports DirectX 11. Although this mode suffered a major bug in the original version of the game, a patch (1.1) has corrected this. We use the game benchmark.
All the options were pushed to a maximum, including tessellation which was pushed to extreme on part of the scenes tested. We measured performance in Extreme mode (which includes the additional DirectX 11 effects) with MSAA 4x and MSAA 8x. The game is updated via Steam.
With the Catalyst 12.4s, AMD has finally, after more than four months, corrected a bug which affected the performance of the Radeons with MSAA in this game, allowing the HD 7970 to overtake the GTX 680 in 8x mode. With its latest drivers Nvidia has however improved performance with MSAA 4x. Note that AMD still doesn’t support CrossFire in this title.
