While the individual components are nothing new, I hadn’t heard of NVidia calling the whole system “AXE”, for Application Acceleration Engines.

NVIDIA® application acceleration engines are highly optimized software modules enabling developers to take maximum advantage of the GPU with valuable, high performance capabilities that are license free to develop with and deploy.

NVIDIA is committed to ensuring engines continue advancing to take maximum advantage of the latest NVIDIA GPU innovations while also maintaining their leading-edge capabilities. Applications employing acceleration engines can rapidly exploit GPU advancements as consistent engine APIs evolve to leverage new methods. In doing so, NVIDIA is empowering developers to deliver the latest capabilities to their users in the shortest amount of time.

The complete suite consists of SceniX (scene graph), CompleX (GPU scaling system), PhysX (GPU accelerated Physics), and OptiX (ray-tracing), along with the usual CgFX and CUDA.
