PhysX is used in over 150 games and is also supported on PC, Xbox 360 and PS3.
Games that use PhysX can create more realistic explosions, character motions, weapon effects, cloth and smoke.
Nvidia SVP of content and technology Tony Tamasi said, “...Adding a PhysX SDK for the Wii is key to our cross-platform strategy and integral to the business model for our licensed game developers and publishers."
Nvidia's news follows the recent announcement that Emergent Game Technologies would be integrating PhysX for Wii developers into its Gamebryo game engine.
