I recently used the NVIDIA PerfSDK for a project and found it to be an extremely useful tool. It allowed me to quickly and easily assess the performance of both 32-bit and 64-bit OpenGL and Direct3D items, as well as view performance statistics. The calibration and repair features of the PerfSDK were especially helpful, as they allowed me to easily identify and address any issues that were negatively impacting the performance of my project. Overall, I found the NVIDIA PerfSDK to be an excellent and comprehensive tool for assessing and improving the performance of graphics drivers.

From the developer:
NVPerfSDK is a component of NVPerfKit that provides a programmatic API for accessing performance counters in the graphics driver and GPU.
It allows you to query performance counters from your own applications, enabling you to build customized profiling functionality. NVPerfSDK is available in 32-bit and 64-bit Windows as well as 32-bit and 64-bit Linux.
