And when I say mayhem .. it's the good kind. NVIDIA just released their PhysX packs and compatible drivers. NVIDIA on Tuesday gave its existing customers a bonus through the GeForce Power Pack, a new set of drivers that expose new features to certain GeForce cards.

The upgrade takes advantage of the more universal nature of the effects processing cores in GeForce 8-, 9- and GTX-series cards to drive tasks that would normally depend on the main CPU. All these cards can now speed up physics in games and other apps that support PhysX; in specially enabled game maps with the new physics turned on, a mid-range GeForce 9800 GTX+ is nearly three times faster than the ATI Radeon HD 4850 that NVIDIA hopes to beat.
