NVIDIA has released the new WHQL version of the PhysX System Software. The PhysX System Software is included with all latest ForceWare graphics drivers but if you don’t have a GeForce graphics card, you have to install the PhysX System Software to use PhysX based applications such as PhyswX FluidMark. PhysX hardware acceleration is available for all GeForce 8-series, 9-series and 200-series GPUs with a minimum of 256MB dedicated graphics memory.

How To Use Multi-GPU with NVIDIA PhysX

In this article, Guru3D explains how to use Multi-GPU with NVIDIA PhysX under Windows XP and Vista. There are 3 ways to use GeForce GPU with PhysX:

  • Standard – one GPU renders both graphics + PhysX (not ideal as you’ll need a lot of GPU horsepower).
  • SLI mode – have two GPUs render both graphics + PhysX (SLI motherboard required)
  • Multi-GPU mode – GPU1 renders graphics and GPU2 renders PhysX (SLI motherboard not required)


Now the trick to use Multi-GPU mode with Vista:

Now there’s a thing you will need to be aware of in the Multi GPU mode, it’s actually a Vista limitation but a second monitor must be attached to enable PhysX running on the second GeForce GPU. You must extend your Windows Vista desktop onto that monitor.

To bypass that issue, most monitors have a standard VGA and a DVI connector, right? Just use both. This limitation is related to the Windows Vista display driver model (WDDM). This limitation does not exist in Windows XP. In NVIDIA’s upcoming drivers, they will be offering a workaround to improve the experience for Windows Vista users.

With a single card or two cards in SLI mode you will not have this problem.

PhysX implementation is highly CPU dependant

FudZilla has done some tests with PhysX FluidMark and has found that GeForce PhysX implementation is highly CPU dependant. I will try to look at this phenomenon (there is certainly something to improve with a better multithreading support). I hope the problem comes from FluidMark and not from GeForce PhysX….


NVIDIA PhysX PowerPack DOWNLOAD

Ecco fatto amici, NVIDIA has released the PhysX PowerPack. What is the PhysX PowerPack? Simply a new ForceWare driver version 177.83 followed by 8 PhysX demos.

The pack is available here: PhysX PowerPack @ NVIDIA – 2781Mb.

Here are two demos from this pack:

NVIDIA PhysX technology Fluid Demo

The primary purpose of the NVIDIA PhysX technology Fluid Demo is to illustrate Smooth Particle Hydrodynamics (SPH). The demo contains two different scenes, the Outdoor and the Logo Scene.

I must say the log scene part is rather impressive: the fluid simulation is really and if you switch the fluid rendering from textured quads (I think it’s that) to polygonal spheres, you can see fluid equations in action!

PhysX Performance with GeForce

FiringSquad takes a look at PhysX performance with GeForce 8/9/GTX200 based graphics cards by testing several games that support PhysX (Unreal Tournament, Warmonger, NKZ, Nurien). The first conclusion is that PhysX is really accelerated on GeForce and the difference between CPU PhysX and GPU PhysX is notable:


To do the tests, FiringSquad has used a modified version of NVIDIA Forceware 177.79. But no indication is given about the modifications on that driver.
They also used the NVIDIA PhysX driver 8.07.18.

SLI PhysX performance is also analyzed but for SLI brings so much power that the tests are CPU-bound. Anyway, SLI PhysX rocks!

After demonstrating beta drivers featuring GPU-accelerated physics on 3DMark Vantage and Unreal Tournament III (GeForce GTX and 9800 boards), Nvidia is getting ready to release the official Windows driver.

This driver will support PhysX acceleration on all capable GeForce 8, 9 and GTX cards, while carrying Microsoft’s WHQL certificate. More importantly, the new ForceWare driver is expanding PhysX support to all currently available PhysX titles on the market, including Ghost Recon 2: Advanced Warfighter, Warmonger and Cell Factor: Revolution.
