Mirror's Edge benchmarks with Radeon HD 4870 plus Ageia card
@ 2009/01/26Ageia once developed the Novodex physics engine and the appropriate PPU (Physics Processing Unit). The latter was supposed to revolutionize future games with unprecedented physics effects and should become the third main component in gaming PCs besides the graphics card and the processor. While the Novodex Engine is still used today, the PPU wasn't able to establish itself due to poor software support - and finally Ageia was bought by Nvidia. Novodex was renamed to Physx and due to the porting to Nvidia's Cuda it cannot just be run on the processor but also on modern Geforce GPUs.
