NVIDIA Unveils NVPerfKit 2.1 Suite

NVIDIA Corporation today announced NVPerfKit 2.1, a comprehensive suite of next-generation performance tools for the debugging and profiling of OpenGL and Direct3D software applications for Windows and Linux.

Developers working on 32- and 64-bit Linux or Windows platforms can now benefit from the same technology that powers the NVIDIA NVPerfHUD performance analysis tool, a profiling and visual debugging heads-up display (HUD) program for Direct3D applications supporting Microsoft DirectX 9.0c and Windows XP on select NVIDIA graphics processing units. According to the press release, developers using NVPerfHUD 4 experience an average performance improvement of 35%, and find an average of 11 rendering bugs.

By offering access to low-level performance counters inside the driver, as well as hardware counters inside the GPU, NVPerfKit 2.1 helps developers determine how applications use the GPU by identifying and confirming resolved performance issues for substantial time savings during application development.

The NVPerfKit 2.1 suite of performance tools includes NVPerfHUD 4; shown here running on the Gamebryo game engine from Emergent Game Technologies.

NVPerfKit 2.1 offers the following components:

  • Instrumented Driver—Interfaces with the graphics API and GPU to provide performance counter data
  • NVPerfHUD—Offers advanced real-time analysis of Direct3D applications
  • NVPerfSDK—Includes an API for accessing GPU signals in applications, sample code and helper classes for OpenGL and DirectX applications, and an NVIDIA Developer Control Panel and instrumented driver
  • NVIDIA Plug-In for Microsoft PIX for Windows
  • GLExpert—Permits debugging of OpenGL usage errors and performance issues
  • Supports PerfMon, Intel VTune, gDEBugger and other analysis tools
NVPerfKit 2.1 supports Windows XP and Linux on NVIDIA GeForce 7 Series GPUs, NVIDIA GeForce 6 Series GPUs, and NVIDIA Quadro FX or more recent NVIDIA GPUs; older GPUs are supported with reduced functionality.

The NVPerfKit 2.1 suite of performance tools is available for download at http://developer.nvidia.com/NVPerfKit. A gallery of NVPerfHUD images spotlighting top game titles is available at http://developer.nvidia.com/object/nvperfhud-screenshots.html.
