NVidia is living on the edge by submitting the first OpenCL Driver for certification by the Kronos OpenCL Working group.

NVIDIA was the first to provide pre-release drivers to its OpenCL Early Access Program participants in April 2009. NVIDIA remains the only vendor today with software and hardware available for developers to program with OpenCL as well as other GPU Computing environments including DirectX Compute, C with CUDA extensions and other languages.
