NVIDIA API (NVAPI)

NVAPI is NVIDIA's core software development kit that allows direct access to NVIDIA GPUs and drivers on all Windows platforms. NVAPI provides support for operations such as querying the installed driver version, enumerating GPUs and displays, monitoring GPU memory consumption, clocks, and temperature, DirectX and HLSL extensions, and more.


NVAPI with Shader Execution Reordering (SER)

SER is a new scheduling system that reorders shading work on-the-fly for better execution efficiency. It is useful on ray traced workloads, as it achieves maximum parallelism and performance from path tracing shaders. It is an NVIDIA API extension, making it very simple and easy to leverage.


SER will be available starting October 12, 2022.
