PhysX and CUDA
NVIDIA seems quite excited about the impending release of a game called Mirror's Edge. The reason for this is that it hopes the game will demonstrate how good physics - the specialised processing of physical events like explosions, collisions, etc - significantly improves the gaming experience.
On the subject of features above and beyond mere gaming graphics processing - a central theme for NVIDIA these days - the audience was also reminded about the CUDA GPGPU architecture and how it now supports OpenCL, DX11 Compute and another mystery API.
Attendees were reminded about NVIDIA's progress on the integrated graphics side of things too.
