[Geeks3D] PhysX FluidMark 1.1.0 Available



PhysX FluidMark 3D Benchmark



About one year ago, the version 1.0.0 of FluidMark was released. One year ago… An update was necessary!

Update (2009.07.23)
FluidMark 1.1.1 Update available HERE.

You can download FluidMark 1.1.0 here:

Remark: This version of FluidMark requires the installation of VS2005 2005 SP1 Redistributable package. You can download this package HERE.

I took FurMark‘s code base and merged it with FluidMark’s own routines. FluidMark 1.1.0 has been compiled with the latest PhysX SDK (v2.8.1 – by the way, seems NVIDIA has a slow update rate for their PhysX SDK ;) ). In stability test mode, you can switch between textured particle and simple point particle by hit the R key.

Simple point particle

FluidMark is a fluid simulation benchmark based on NVIDIA PhysX engine. The fluid simulation used the SPH or Smoothed Particle Hydrodynamics method where interparticle forces are considered (SPH requires more CPU or GPU horsepower!). I added a command line parameter to disable SPH method. In that case, the fluid is seen as a set of independent particles. To ease your geek life, I added a file called Start-No-SPH.bat

The main startup GUI (graphical user interface) is:

PhysX FluidMark 3D Benchmark

FluidMark’s fluid simulation is based on NVIDIA PhysX engine. This engine is hardware accelerated (via CUDA) for all GeForce 8/9/GT200 with the latest graphics drivers. The graphics drivers for GeForce install the latest version of CUDA and PhysX runtimes. For all other cards that are not CUDA-compliant (GeForce 5/6 or Radeon for example) the PhysX engine runs in software mode. So if you can’t start the benchmark, be sure to have the latest PhysX runtimes (9.09.0428 at the time of writing).

FluidMark exploits OpenGL for graphic acceleration and requires an OpenGL 2.0 compliant graphics card: NVIDIA GeForce 5 and and higher, AMD/ATI Radeon 9600+ and higher or a S3 Graphics Chrome 400/500 series with the latest graphics drivers.

In pure software mode, FluidMark is also an excellent CPU benchmark. Try it! To disable PhysX GPU acceleration (GeForce 8 and higher), open NVIDIA control panel and select the Disabled radio button in 3D Setting / PhysX Configuration:

Here are some scores I got with my GeForce GTX 295:

1/ Software PhysX – SLI disabled – Score = 1796 points

FluidMark score + PhysX disabled

FluidMark score + PhysX disabled

2/ Hardware PhysX – SLI disabled – Score = 11551 points

FluidMark score + PhysX disabled

FluidMark score + PhysX disabled

3/ Hardware PhysX – SLI enabled – Score = 11532 points

FluidMark score + PhysX disabled

FluidMark score + PhysX disabled

FluidMark 1.1.0 changelog:

  • New: simple color point rendering mode (press the R key in stability test).
  • New: use the code base than FurMark.
  • New: command line parameter (/no_sph) to disable SPH fluid simulation method.
  • Change: compiled with NVIDIA PhysX SDK 2.8.1.
  • Bugfix: minors bugs fixed
