NVIDIA ShaderPerf allows you to determine how expensive a given vertex or pixel shader might be across a range of GPUs and drivers.
NVIDIA ShaderPerf is a command-line shader profiling utility and C API that reports detailed shader performance metrics for a wide range of GPUs.
ShaderPerf includes several new features:
- GeForce 8 series support
- Pixel Shader Differencing
- Vertex Shader Analysis
Thank you NVIDIA!
