A BFG Physx card. PhysX is an open-source [1] realtime physics engine middleware SDK developed by Nvidia as part of the Nvidia GameWorks software suite.. Initially, video games supporting PhysX were meant to be accelerated by PhysX PPU (expansion cards designed by Ageia).
The Visual FX, PhysX, and Optix SDKs provide a wide range of enhancements pre-optimized for Nvidia GPUs. [2] GameWorks is partially open-source . [ 3 ] The competing solution being in development by AMD is GPUOpen , which was announced to be free and open-source software under the MIT License .
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 important distinction between the two is that effect physics do not affect gameplay (dust or small debris from an explosion, for example); the vast majority of physics operations are still performed in software. This approach differs significantly from the PhysX SDK, which moves all calculations to the PhysX card if it is present.

Bullet is a physics engine which simulates collision detection as well as soft and rigid body dynamics.It has been used in video games and for visual effects in movies. Erwin Coumans, its main author, won a Scientific and Technical Academy Award [4] for his work on Bullet.
Version 3.0 also added the Bullet physics engine in addition to the engine's built-in 3D physics back end and was the first version of Godot to be included in Debian. Godot 3.1 was released on 13 March 2019, with the most notable features being the addition of statically typed § GDScript , a script class system for GDScript, and an OpenGL ES 2 ...
OptiX has been integrated into the GameWorks developers library along with PhysX and other CUDA powered graphics engines and frameworks. [8] Adobe After Effects CC [9] Daz Studio had OptiX Prime Acceleration since its Iray integration, however support was removed in version 4.12.1.8 [10] Luxrender 2.5: up to 600% acceleration [11]
