NVIDIA has, more often than not, been extremely helpful when it comes to making sure it is supportive of the desktop market. Today’s post just goes to reaffirm this, I think.
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.
NVPerfKit 2.1 now includes support for 64-bit Windows platforms, as well as 32-bit and 64-bit Linux platforms. Other improvements include an updated installer, Release 90 driver support, enhancements to NVPerfHUD, and more.
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… [Source: LinuxLookup]
