Passion for physics

On September 30, AMD announced the start of development of the Open Physics Initiative, a technology that will compete with nVidia PhysX.

Pixelux Entertainment, the developer of the Digital Molecular Matter (DMM) “physical system,” which was first used in LucasArts Star Wars, became the partner of AMD in this business. Pixelux’s task will be to integrate its technology with Bullet , a free open-source physics engine.

Bullet is currently the third most popular physics engine after Havok and PhysX. However, AMD and Pixelux might well make it more common.

By the way, it was recently revealed that the drivers for nVidia video accelerators, starting from 186.18, have disabled the possibility of using GeForce 8xxx, 9xxx or 2xx cards as a separate physical processor in case a non-nVidia GPU is installed in the system.

Actually, the new drivers will not allow using any old, simple and cheap GeForce for PhysX, if the main video card is Radeon. This is another reason to "scratch" and change the balance of power. What AMD is trying to do.
