Nvidia will this week was showing in-game physics code calculations being run on a graphics processor, the first time this has been done in public, the company claimed today. We have two exclusive small movies available which will show this in action. Havok FX will have support for both a single NVIDIA GPU as well as two or more GPUs running in SLI mode. An SLI configuration will allow for a user to dedicate an entire GPU to graphics and one to physics. If the Havok FX engine is not utilizing the GPU, NVIDIA claims that the SLI configuration can still be used for increased graphics performance.
