GPU ShaderAnalyzer (GSA for short, pronounced Gee-Zah) is a tool for profiling real time shaders (Direct3D 9/10 and OpenGL). You can use this tool on both NVIDIA and ATI hardware (I did a test on my GeForce GTX 280 and the assembly shader code has been generated) but I guess it’s better to use it on a Radeon! You must be logged to AMD Developer Central in order to download this tool.
* Support for Catalyst driver 8.10
* Added -NoGeometryShader (G) option for a DX10 shader to the command line parameter
