Overclockers hack PhysX effects in GRAW2 to render on CPU
 

GRAW2 is heavily advertised as a game that uses real-world physics to enhance gameplay, and for full enjoyment in the game environment, you should own an Ageia PhysX card. A forum member under the name of Ergonomics appears to have hacked the game - by very simple edit of an XML file - to enable PhysX-only effects on a CPU, so avoiding the need for Ageia's PhysX card.
