Just a little performance test of the latest ForceWare 177.92 BETA versus the latest ForceWare 177.83 WHQL using oZone3D.Net OpenGL Benchmarks Suite and Lightsmark2008:
|Release 177.83||Release 177.92||Difference|
|Soft Shadows Branching OFF||6054||5817||-4%|
|Soft Shadows Branching ON||10198||9542||-6.5%|
|FluidMark GeForce PhysX||9626||9579||-0.5%|
|FluidMark Software PhysX||1495||1503||0%|
Well… many websites have claimed that release 177.92 brings a boost in performance. Maybe in Direct3D (I also ran Aquamark and 3DMark2006 under WinXP and I didn’t see differences) under Vista. But in OpenGL, there is no performance gain.
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!
NVIDIA has released a new set of drivers that add support for PhysX acceleration on all GeForce 8-series, 9-series and 200-series GPUs with a minimum of 256MB dedicated graphics memory. The PhysX System Software 8.08.01 is automatically installed with this driver package that explains the big size of the driver
