Ozone3D released the first version of PhysX FluidMark - this is a new benchmark focused on the NVIDIA PhysX technology. This program supports software and hardware-rendering. The use the hardware rendering mode you'll need a AGEIA PhysX card or a NVIDIA GeForce 8/9/GTX 200 graphics card with PhysX drivers installed.
PhysX FluidMark is a physics benchmark based on NVIDIA PhysX engine. This benchmark performs a fluid simulation by imitating the renderering of lava. Real physics parameters such as viscosity are used. SPH (Smoothed Particle Hydrodynamics) algorithm is enabled to increase the realism of the simulation.
