Nvidia GF100 SPH PhysX Fluids demo
Impressive video of realtime Smoothed Particle Hydrodynamics (SPH) PhysX Fluid simulation demo, running on GF100 GPU, was uploaded to YouTube by Nvidia recently.
According to certain slides, this demo is using 128 000 particles, running on 141 frames per second.
First game that made use of PhysX SPH, Cryostasis, simulated 30,000 water particles at average 30 frames per second on the GT200 architecture. Next title with extensive SPH Fluids effects is going to be Metro 2033, as we heard.
GPU PhysX in Dark Void: comparison video
Dark Void is interesting title – at least from GPU PhysX perspective. It’s using brand new APEX Turbulence module for dynamic real time fluid smoke and particles simulations, which is looking much more realistic and natural then usual SPH-based smoke we’ve seen, for example, in Batman: Arkham Asylum.
Hovewer, more immersive gameplay came at great cost – Dark Void is most demanding GPU PhysX game currently. Consider dedicated GTX260 GPU as minimum requirement for High PhysX settings.
In general, there are four PhysX modes in the game:
PhysX – Off: standart physics stuff, calculated on CPU – ragdolls, some dynamic rigid bodies, some particles. Default level for console versions.
PhysX – Low: adds some dynamic particles – chunks and debris from bullet impacts, physically simulated sparks for Hypercoil and Magnetar weapons, additional shards for destroyed enemies. We’ve seen such effects before, in almost every single GPU PhysX game, but this time there is really huge amount of particles, and they are not dissapearing for like half a minute or so.
Remark: The Low setting is the only setting that can be used to compare CPU PhysX effects versus GPU PhysX.
PhysX – Medium: additionally enables turbulence particle simulation for Disintegrator Gun. Each vaporazed enemy emits 30 000 particles, and there can be several simultaneous effects on-screen at once. As ragdoll moves and rotates it imparts linear and angular forces into the fluid simulation, thus each disintegration is unique.
This mode is NOT available for CPU calculations, you just won’t be able to enable it without appropriate Nvidia GPU.
PhysX – High: includes all additional physics effects, and adds dynamic fluid smoke for Jetpack in Hover mode. Smoke simulation uses up to 100 000 particles, which are emitted every time whenever there is a change in applied power (i.e. the jetpack is turned on or off). This mode is NOT available for calculations on CPU.

Dark Void PhysX trailer
World’s first PhysX trailer from Dark Void was uploaded to YouTube.
It’s showcasing some nice particle effects for Desintegrator Gun and Jetpack, made with APEX Turbulence module. You also can notice small chunks and debris, breaking off from destroyed enemies.
Update: hands-on impression by Shacknews
The additional special effects kicked in by turning on PhysX are all just cosmetic touches but boy do they make an impact. Dark Void’s jet pack puts the turbulence modelling to good use as each of the twin exhaust plumes swirls and realistically responds to momentum independently. It looked strikingly realistic as I pulled off aerial manoeuvres.
PhysX also provides a number of flashy weapon effects. Hitting an enemy with the disintegrator gun, for example, cause them to disperse in a wisp of particles on the wind. As nice as the console editions look, these effects give the PC version a real visual pop.
With both PhysX and 3D turned on, though, I found the combination distracting. The turbulent jet exhaust that had looked so good became a distraction as it didn’t quite line up correctly with the rockets. All the particle effects from weapon fire still looked pretty but also noticeably increased my eyestrain. I’m not sure whether this was due to their taxing the system or my sight but either way it was uncomfortable.
For my money, I’d probably play the game through with the PhysX effects turned on and leave the 3D as an occasional thing to turn on and fly around a level that it works well with.

How to set up Hybrid PhysX system: video guide
User Containforum has uploaded video guide on how to set up Hybrid ATI+NV PhysX system. It contains overview of all necessary drivers and mods, where to download them, and how to make them working together.
Other guides you may refer to: Link#1 | Link#2 | Link#3 | Link #4 | Link#5 | Link#6 | Link#7 <- it’s recommended to start from newer links.
Hybrid PhysX systems benchmarks: HD4870/5870+9500/9600GT | HD4850/5750+9800GT | HD5870+GT220 | 2xHD5870 + 9800GT | HD5870/GTX285 + 9800GT
Update: Catalyst 10.2 and extended display error fix – in addition, you’ll be able to use dedicated NV GPU for PhysX without necessity to extend display.
