Arkham was tested at 1920×1080 with no anti-aliasing and 16x anisotropic filtering. All in-game settings were at their maximum level and for the NVIDIA configurations PhysX was set to High.
Arkham City is one of those games which makes us lean towards using an NVIDIA GPU in the Commander thanks to the use of PhysX. With this setting enabled we get added visual effects such as better cloth and paper use which really add to the immerseiveness of the game. With the latest patch and at our chosen settings on a resolution of 1920×1080 we get great performance.
Here is how the game looks at our tested settings.
