NVIDIA PerfKit is a comprehensive suite of performance tools to help debug and profile OpenGL and Direct3D applications.

It gives you access to low-level performance counters inside the driver and hardware counters inside the GPU itself. The counters can be used to determine exactly how your application is using the GPU, identify performance issues, and confirm that performance problems have been resolved.

NVIDIA PerfKit includes support for 32-bit and 64-bit Windows XP and Vista platforms.

The performance counters are available directly in your OpenGL and DirectX applications and a plug-in supporting Microsoft PIX for Windows is also provided, giving you low-latency access to PerfKit performance counters directly from the driver.

NVIDIA PerfKit consists of the following components:
