NVIDIA ShaderPerf

NVIDIA ShaderPerf is a command-line shader profiling utility and C API that reports detailed shader performance metrics for a wide range of GPUs. 

A graphical user interface (GUI) for shader performance analysis is available in FX Composer 2.5, and was built using the ShaderPerf API.

ShaderPerf 2.0 includes several new features:

• GeForce 8 series support
• Pixel Shader Differencing
• Vertex Shader Analysis

ShaderPerf outputs the following for any shader that you analyze:

• Cycle count
• Register usage
• Driver-optimized shader instruction list
• Vertex and pixel throughput estimates
