Used in more than 500 games on multiple platforms, NVIDIA PhysX is one of the most popular physics engines for game development. The PhysX SDK is a proven solution for gameplay physics and simulation-driven effects. It is integrated into major game engines such as Unreal Engine 3 and 4, Unity, AnvilNext, Stingray, Dunia 2 and REDengine.

NVIDIA PhysX Clothing and Destruction are integrated into the Unreal Engine 4. PhysX Clothing and Destruction effects can be seen in games such as: Batman: Arkham Asylum, Batman: Arkham City, Bioshock Infinite, Borderlands 2, Lords of the Fallen, Monster Hunter Online, Daylight, and Witcher 3.

A major component of the NVIDIA GameWorks library, the latest PhysX version (3.3.4) is our best ever, with improved stability and performance. Features include constrained rigid body dynamics, collision detection, scene queries, character controller, particles, vehicles and much more.

The PhysX software development kit (SDK) is free on Windows, Linux, OSX, iOS and Android on (link will only work for registered users).
