It is already know that ATI and NVIDIA companies develop technologies witch allow to accelerate with the aid of video card not only scientific and engineering calculations, but also physical effects in games. Ally of both companies in this sphere must become havok company , which develops the specialized engine havok FX.
As reported associates on exhibition ceBIT 2007 AMD and Havok companies conducted the united demonstration of crossFire physical possibilities using motherboard on base of chipset AMD 580X CrossFire with pair video card radeon x1900 XTX. Other details about test configuration was not communicated. A scene with several brick destruction was used as demo- program.
The speed of tracing scene composed 40-100 frames per second with the calculation of physical effects using graphic chips radeon x1900 XTX.
Here we should note that if design data were calculated by the central processor, then speed fell to 3-10 frames per second.
Certainly, on the base of given example it is early to make conclusion about the physical capability of Crossfire , such card is not always faster 10 times than the central processor , but it is already possible to estimate the advantages of this technology . It is assumed that one of the first games with havok FX support and physical crossfire will become London: Hellgate, announcement of which is planed on June. It is necessary to assume that SLI supporters also can use the advantages of havok FX engine. Related Products :
