Is there a tool available that can do performance profiling of OpenGL shaders?

---

nVidia PerfWorks can. They also have FX Composer, which includes some profiling with a graphical front-end (but FX Composer is now basically discontinued--you can still download it, but it's no longer being updated).

AMD/ATI's GPUPerfAPI and GPUPerfStudio provide similar capabilities. They also have GPU ShaderAnalyzer to do static analysis, but I believe it's restricted to DirectX shaders, not OpenGL.

If you run on Nvidia hardware there is also Nsight for Visual Studio resp. the standalone Nsight Graphics.

AMD's GPUPerfStudio even works without AMD hardware but you only get the API tracer (and the static shader analyzer if you use DirectX). The frame debugger and profiler tools depend on their hardware of course.

For Intel there is GPA. It doesn't support shader micro profiling though. There is also the static (i.e. does not require hardware) Intel Shader Analyzer but not sure if it provides more than just the assembly: http://shader-playground.timjones.io/749ef0d908128a0ae8a824b93381bbf1

RenderDoc does not really have profiling capabilities at this point due to lack of time. But some Intel perf counters for OpenGL have been added recently.
