Batman: Arkham City PC DX11 and PhysX Preview

Nvidia has released a comparison video on youtube which displays some of the effects available when enabling PhysX. In the video below you will see extra debris such as glass or newspapers as well as smoke that reacts to the player as they run through it.

Furthermore, there are some DirectX 11 screens floating on the web. The first image is without DX11 and the second image is with DX11. Arkam City utilizes tessellation to increase the detail of certain objects in a scene. In this particular example you can see how the vegetation in the background is more detailed when taking advantage of DX11 effects.
