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 first video game to use PhysX technology is The Stalin Subway , released in Russia-only game stores in September 2005.
Games wishing to take advantage of the PhysX PPU must use AGEIA's PhysX SDK, (formerly known as the NovodeX SDK). It consists of a general purpose RISC core controlling an array of custom SIMD floating point VLIW processors working in local banked memories, with a switch-fabric to manage transfers between them.
Ageia, founded in 2002, was a fabless semiconductor company.In 2004, Ageia acquired NovodeX, the company who created PhysX – a Physics Processing Unit chip capable of performing game physics calculations much faster than general purpose CPUs; they also licensed out the PhysX SDK (formerly NovodeX SDK), a large physics middleware library for game production.
The game was designed to show off what AGEIA PhysX cards are capable of. The cards are designed for physics processing, which allows the video game that uses them to have a physics-based gameplay. The cards are designed for physics processing, which allows the video game that uses them to have a physics-based gameplay.
The term was coined by Ageia's marketing to describe their PhysX chip to consumers. Several other technologies in the CPU-GPU spectrum have some features in common with it, although Ageia's solution was the only complete one designed, marketed, supported, and placed within a system exclusively as a PPU.
PhysX: For physics, destruction, particle and fluid simulations. OptiX: For baked lighting and general-purpose ray-tracing. Core SDK: For facilitating development on Nvidia hardware. In addition, the suite contains sample code for DirectX and OpenGL developers, as well as tools for debugging, profiling, optimization, and Android development.

On January 5, 2007, Nvidia announced that it had completed the acquisition of PortalPlayer, Inc. [55] In February 2008, Nvidia acquired Ageia, developer of PhysX, a physics engine and physics processing unit. Nvidia announced that it planned to integrate the PhysX technology into its future GPU products. [56] [57]
