PC Games Hardware has their own look at the advantages in the Windows PC edition of Batman: Arkham City, the upcoming action/stealth sequel to Batman: Arkham Asylum talking with Ben Wyatt of Rocksteady Studios on how the Windows edition will differ from the console versions. The game's Technical Director tells them that the game will not support DirectX 10, and outlines the following advantages its DirectX 11 graphics will enjoy over running it under DirectX 9:

Compared to the DX9 mode, the DX11 mode will have:

1. More geometric detail on tessellated objects, such as architectural details, vines and other organic shapes. The main difference will be no visible triangles and additional displacement-mapping detail. The difference will be mostly noticeable at to object's silhouettes, as well as playing the game with 3D Vision (which makes the displacement-mapping detail much more obvious).

2. A more pronounced contact occlusion due to the DX11 SSAO (especially noticeable on the PhysX debris, leaves, and paper), which makes certain objects look more in contact with the ground (as opposed to floating above the ground).

3. Contact-hardening soft shadows for the dynamic shadows cast by the player-controlled character (either Batman or Catwoman). On DX9, this dynamic shadow does not harden on contact, which looks less realistic.
