A post on the GeForce website discusses NVIDIA GameWorks support in Batman: Arkham Knight, showing off some NVIDIA-specific hardware effects in a new. trailer. Here's word:

Batman: Arkham Asylum, Arkham City and Arkham Origins each featured advanced NVIDIA GameWorks effects that greatly enhanced graphical fidelity and immersion, so it should come as no surprise that the upcoming Batman: Arkham Knight is similarly enhanced.

We’ll be revealing further NVIDIA GameWorks features in the near future, as well as other uses for the effects you’ve just seen. For now, here’s a quick rundown on the effects presented in our GeForce GTX PC tech trailer:

• Interactive Smoke & Fog utilizes the many CUDA Cores on your GeForce GTX PC to render interactive particle effects that would impossible to create on a CPU. Each effect can be manipulated by character movement, environmental conditions and external forces, and moves realistically around and across surfaces. Such effects are further enhanced by Particle Shadow Mapping, enabling particle self-shadowing and the casting of shadows on surfaces.
• Like Interactive Smoke & Fog, Interactive Paper Debris uses the power of modern NVIDIA GeForce GTX GPUs to render pieces of paper and other pieces of debris that react realistically to character movement, environmental conditions and external forces, heightening immersion as Batman and friends battle thugs.
• Enhanced Rain is a new NVIDIA GameWorks effect created specially for Batman: Arkham Knight. Using the extra performance available on PCs, the new visual effect spawns additional rain particles with simulated velocity when Batman’s cape opens for flight. For a real world comparison, quickly close and re-open a wet umbrella and observe how the droplets of water shoot off with some force.
