Several GeForce 9 series will have a lower power consumption when idle with an upcoming BIOS update. I’m sure we can rely on Expreview to check that feature…

This is the continuation of the previous post on PhysX Performance with GeForce.
The PhysX Pack provided by NVIDIA contains a PhysX fluid demo:
The primary purpose of the NVIDIA PhysX Fluid Demo is to illustrate Smooth Particle Hydrodynamics (SPH)-based particle simulation technology accelerated by the NVIDIA GPU.
The pack also contains the Unreal Tournament III PhysX Mod:
The PhysX pack will be publicly available on August 12, 2008. The package consists of a new graphics driver that will enable PhysX on graphics cards equipped with GeForce 8, GeForce 9, and GeForce GTX GPUs, a downloadable PhysX software pack containing free Unreal Tournament 3 maps, the full version of NetDevil’s Warmonger, NVIDIA demos, and a first look at Object Software’s Metal Knight Zero and Nurien Software’s Nurien social-networking service.

PhysX Performance with GeForce
Categories: Graphics Cards, NVIDIA PhysX, PhysX Tags: cpu, geforce 8, geforce 9, geforce gtx 200, geforce physx, gpu, nkz, nurien, physx, physx performance, unreal tournament, warmonger
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!

WHQL-certified PhysX drivers on August 5th
Categories: NVIDIA PhysX, PhysX Tags: geforce 8, geforce 9, geforce gtx, NVIDIA, physx, physx driver, whql driver
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.

[English]PhysX on GeForce using CUDA[/English][French]PhysX sur GeForce avec CUDA[/French]

[English]
The implementation of PhysX has been done using CUDA. Thanks to CUDA, NVIDIA driver team has quickly converted Ageia’s PhysX functions. All GeForce 8, 9 and GTX200 will be PhysX compliant. However, one thing won’t be GPU-accelerated: rigid bodies. According to Manju Hedge, former Ageia’s CEO, GeForce 8/9/GTX200 are more powerful and faster than the current PhysX PPU.

L’implémentation a été faite grâce à CUDA (extension du C pour exploiter le GPU comme unité de calcul) qui a permis une conversion rapide de l’API qui devient ainsi compatible avec toutes les GeForce 8 et 9 ainsi qu’avec les futures GeForce GTX 200. D’entrée de jeu, les GeForce GTX 260 et 280, et leurs prédécesseurs, devraient donc être compatibles avec le subset de l’API PhysX global, comme l’est le PPU, avec une différence cependant: le portage des rigid bodies n’a pas encore été effectué et cette fonctionnalité ne pourra donc pas, pour le moment du moins, être accélérée par le GPU. Selon Manju Hedge, ancien CEO d’Ageia, les GeForce 8 et 9 haut de gamme (et bien évidemment les futures GeForce GTX 200) sont nettement plus véloces que le processeur PhysX.
