The fluid simulation uses the SPH or Smoothed Particle Hydrodynamics method where interparticle forces are considered (SPH requires more CPU or GPU horsepower!). You can download PhysX FluidMark here:Webmasters: hotlinking is not allowed, please use the post url as download link.[download#136#image]The main feature of this new version is the support of multi-core CPU. Actually multi-core CPU is a trendy way to tell that PhysX FluidMark is now multi-threaded. FluidMark has several threads: the main app thread (GUI), the rendering thread and one or several PhysX threads. PhysX threads are only created when Multi-core PhysX is checked. The support of multi-core CPU can be seen as a consequence of these two news: AMD and NVIDIA.Actually there are two kind of threading when Multi-core PhysX is checked:1 – PhysX GPU: this is the default mode. In that case, only one PhysX thread is created for the physics simulation.2 – PhysX CPU (Force PhysX CPU checked): all PhysX simulation is done on the CPU. In that case, one or several PhysX threads are created according to the number of selected emitters.The following screenshot shows the multi-core PhysX CPU in action: 120000 particles are simulated on a Core i7 960 with hyper-threading enabled (8 cores):As you can see, multi-core CPU PhysX works fine 😉 I will publish in a next post the results for some GPUs and CPUs.Don’t hesitate to post your scores for various settings in the comment section… Other new things concern the particle rendering. In previous versions, particles were rendered using billboarded quads (4 vertices per particle). This technique works fine but is rather CPU greedy. So the modern alternative to these billboarded quads is the point sprite. With point sprite, there is only one vertex per particle, the billboarding technique allowing the quad to face the camera) being done by the GPU. Point sprites bring a significant increase of rendering speed. That’s why I added a Heavy PhysX checkbox. When checked, Heavy PhysX sets the particle emitter rate to 2000 particles/sec whereas by default, the rate is 500 particles/sec. The particle rate can be set in FluidMark configuration file (startup_options.xml).Lava particles – F3Simple point particles – F4This version of FluidMark has been compiled with the latest PhysX SDK v2.8.3.21.FluidMark fluid simulation is hardware accelerated for all GeForce 8, 9, GTX200 and GTX400 series 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 5/6/7 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.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

First video game to use PhysX technology is The Stalin Subway, released in Russia-only game stores in September 2005.[5] In 2008, Ageia was itself acquired by graphics technology manufacturer Nvidia.[6] Nvidia started enabling PhysX hardware acceleration on its line of GeForce graphics cards[7] and eventually dropped support for Ageia PPUs.[8]PhysX SDK 3.0 was released in May 2011 and represented a significant rewrite of the SDK, bringing improvements such as more efficient multithreading and a unified code base for all supported platforms.[2]At GDC 2015, Nvidia made the source code for PhysX available on GitHub, but required registration at developer.nvidia.com.[9] The proprietary SDK was provided to developers for free for both commercial and non-commercial use on Windows, Linux, macOS, iOS and Android platforms.[10] On December 3, 2018, PhysX was made open source under a 3-clause BSD license, but this change applied only to computer and mobile platforms.[11]On November 8, 2022, the open source release was updated to PhysX 5, under the same 3-clause BSD license.[12]In February 2025, support for 32-bit CUDA applications was deprecated for the GeForce RTX 50 series, rendering GPU-accelerated PhysX nonfunctional in 32-bit titles.[13] This resulted in GPU PhysX options to be processed by the CPU, causing a degradation in performance, in titles such as Mirror's Edge and Borderlands 2.[14]The PhysX engine and SDK are available for Microsoft Windows, macOS, Linux,[11] PlayStation 3,[15][16] PlayStation 4,[17] Xbox 360,[18] Xbox One,[19] Wii,[20] iOS and Android.[11]PhysX is a multi-threaded physics simulation SDK. It supports rigid body dynamics, soft body dynamics (like cloth

However, after Ageia's acquisition by Nvidia, dedicated PhysX cards have been discontinued in favor of the API being run on CUDA-enabled GeForce GPUs. In both cases, hardware acceleration allowed for the offloading of physics calculations from the CPU, allowing it to perform other tasks instead.PhysX and other middleware physics engines are used in many video games today because they allow game developers to save development time by not having to write their own code that implements classical mechanics (Newtonian physics). To do, for example, soft body dynamics.[2]What is known today as PhysX originated as a physics simulation engine called NovodeX. The engine was developed by Swiss company NovodeX AG, an ETH Zurich spin-off.[3] In 2004, Ageia acquired NovodeX AG and began developing a hardware technology that could accelerate physics calculations, aiding the CPU. Ageia called the technology PhysX, the SDK was renamed from NovodeX to PhysX, and the accelerator cards were dubbed PPUs (Physics Processing Units).[4]In its implementation, the
