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 is available separately for 3 target platforms. PC packages includes support for 32-bit and 64-bit Windows 8, Windows 7, and Vista platforms. Android packages includes support for NVIDIA Tegra TK1 devices running Android OS. Linux for Tegra packages includes support for NVIDIA Jetson TK1 development platform.

The performance counters are available directly in your OpenGL and DirectX applications, giving you low-latency access to PerfKit performance counters directly from the driver.

The latest version of NVIDIA PerfKit does not contain NVIDIA PerfHUD. PerfHUD functionality has been added to Nsight™ Visual Studio Edition. NVIDIA® Nsight™ Development Platform, Visual Studio Edition is a graphics debugging and profiling environment integrated into Visual Studio.

We recommend all PerfHUD users to migrate to using the latest versions of Nsight™ Visual Studio Edition. All future development of PerfHUD will be deprecated as a result of full PerfHUD feature support in Nsight™ Visual Studio Edition. The last released version of PerfHUD is available here.


Select the appropriate platform:
 Desktop PC   Android   Linux for Tegra 
Android and Linux for Tegra packages are only available as part of AndroidWorks and Jetson TK1 Development Pack respectively.
