Cryostasis is a game (available on February 2009) that uses massively NVIDIA’s PhysX technology. Cryostasis is the first game to use the GPU to calculate fluid simulation using smoothed particle hydrodynamics (SPH). If you can’t wait to see SPH in action, just grab PhysX FluidMark. This benchmark uses SPH to render the lava.
The guys at Legit Reviews have done some tests with Cryostasis and a system with two graphics cards:
– one card for 3D rendering (GeForce GTX 260 core 216 vs Radeon HD 4870)
– one card for PhysX (GeForce 9600 GT)
