From PhysX Wiki
|NVIDIA PhysX SDK 2.x|
|Latest public versions|
|Mac OS X:||2.8.4|
NVIDIA PhysX SDK 2.x (PhysX Software Development Kit, versions 2.3.0 - 2.8.4) - physics simulation engine, currently owned and developed by NVIDIA. Supplementary tools like DCC plug-ins, profilers and debugging applications are included.
Supported plaforms: Windows, Linux, Mac OS X, Xbox 360, PS3, Wii, Android and iOS.
PhysX SDK is widely adopted by developers - over 300 released games are using it to simulate in-game physics, also PhysX is integrated into Unreal Engine 3, Unity 3D, Gamebryo and others game engines.

PhysX SDK 2.8.x platform availability is organized as follows:
|Platform||PhysX SDK Binary|
|Windows PC||Free for commercial and non-commercial use without restrictions|
|OS X, Linux*, Android*||Free for non-commercial or educational use. Free for commercial use if gross revenue, associated with application, is less than $100K.|
* available by request
For more details on PhysX SDK 2.x binary access, source licenses, paid support options or other supported platforms (consoles, mobile devices) please contact NVIDIA via
After introduction of PhysX SDK 3.x, SDK 2.8.x will be supported for titles already in development, but is otherwise deprecated.
- AgPerfMon tool provides performance profiling capabilities.
- PhysX Visual Debugger has ability to capture and record data from PhysX SDK, for further debugging and analysis.
- DCC plug-ins for 3ds Max and Maya are supporting PhysX scene export.
- APEX Framework, that sits on top of PhysX SDK, can be used for creation, authoring and scaling of high level physics effects, like objects destruction, dynamic character clothing and particle effects.
Originally, PhysX SDK was known as NovodeX physics engine, developed by Swiss company Novodex AG. Ageia has acquired Novodex AG in 2004, with all the personnel and software developments. Novodex SDK v. 2.3 with PPU support was renamed to PhysX SDK.
After Nvidia bought Ageia in February 2008, PhysX SDK was augmented to achieve hardware physics acceleration on Nvidia GPUs.
|PhysX SDK 2.8.4||August 16, 2010||This SDK features improved CPU/PS3/Xbox 360 cloth solver (up to x2-x3 performance gain), driverless model, SSE2 support, extended GPU memory allocation control and various bug-fixes.|
|PhysX SDK 2.8.3||October 1, 2009||64-bit support, hierarchical position based dynamics solver and constrained cloth functionality (for APEX Clothing) were added. In this version was removed support for Ageia PhysX PPU.|
|PhysX SDK 2.8.1||March 30, 2008||Includes bug-fixes, and new parameters and features for joints and AABB tree prunning structures. At the time, custom CUDA code was added to PhysX SDKs 2.8.1, 2.8.0 and 2.7.3 to support GPU acceleration.|
|PhysX SDK 2.8.0||February, 2008||New Force Fields system was added. Character Controller source code was provided. Additions to contact report, multi-threading, cloth and cooking features. Added support for fluids and Xbox 360 and PS3.|
- PhysX SDKs versions from 2.3.2 to 2.8.3 are requiring installation of software package called PhysX System Software on both developer's and end-user's machine to operate properly. PhysX SDK 2.8.4 has introduced new driverless model, and is not binded with PSS installation anymore.
