Johnston PhysX Engine 
 
  The Johnston PhysX Engine, is a high end open source physics engine  under development in Burlington, Canada. It is designed for computer and video games by allowing interaction between objects or other devices in real-time by using dynamic simulation and other features such as quantum physics, and ragdoll physics. Instead of integrated standalone physics, in forced hardware, the Johnston PhysX Engine uses updated & modified nVidia forceware drivers, allowing for the GPU to directly work with the updated physics mod engine rather than running with standard nVidia quantum built-in physics.  
 
   Version 1.0 - 1.9 
  Includes features such as dynamic and real-time motion physics and also allows for improved gameplay and FPS (frames per second) during gaming and computing.
