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.
The performance counters are available directly in your OpenGL and DirectX applications and in tools such as Intel VTun for Windows and Graphic Remedy’s gDEBugger via the Windows Management Instrumentation (WMI) Performance Data Helper (PDH) interface. A plug-in supporting Microsoft PIX for Windows is also provided, giving you low-latency access to PerfKit performance counters directly from the driver.
