Developer’s description: NVPerfKit 6.1 – Performance tools to help debug and profile OpenGL and Direct3D applications.

NVPerfKit 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? VTune? 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 NVPerfKit performance counters directly from the driver.NVPerfKit consists of the following components:Instrumented Driver Interfaces with graphics API and GPU to provide performance counter dataAutomatically installed by NVPerfKit installerNVPerfHUD Advanced real-time analysis of Direct3D applicationsNVPerfSDK API for accessing GPU signals in your applications Sample code and helper classes for OpenGL(tm) and DirectX(tm) applications NVIDIA Developer Control Panel and instrumented driverNVIDIA Plug-in for Microsoft PIX for WindowsGLExpert Debug OpenGL usage errors and performance issues Support for PerfMon, Intel(r) VTune(tm), gDEBugger, and other analysis toolsgDEBugger 30-day trial version… click here for more…
