[English (United States)] Minor update: The previous release of NVShaderPerf for 71.80 installed some shared libraries that were incompatible with the current release of FX Composer. This release fixes that problem. ----- The NVShaderPerf command line utility uses the same technology as the Shader Perf panel in FX Composer to report shader performance metrics. It supports DirectX and OpenGL shaders written in HLSL, GLSL, Cg, !!FP1.0, !!ARBfp1.0, PS1.x and PS2.x. You can get performance reports for your shaders on the entire family of NVIDIA GPUs, including cycle count, register usage and pixel throughput metrics. This release fixes issues with sending output and error messages to the same file and allows the user to override the file type determination (based on exension) so any file extension can be used. File supported type options include: glsl, glsl_ps (same as glsl), hlsl, hlsl_vs, hlsl_ps (same as hlsl), cg, cg_ps (same as cg), asm (will look at asm header (ie ps_2_0)). Other types are enumerated in the help message and are reserved for future functionality.
