Profiling OpenGL ES in Windows

I'm trying to do some profiling on my OpenGL ES code. Somewhere in my GPU pipeline (a shader I believe) is causing a huge delay. Which is the best profiler I can use? Is this one a good option? is there one I can use directly within Visual Studio?

If you have a GPU performance issue on IOS, the best is to use XCode tools to profile it directly on device, running the app from Xcode and then doing a frame capture to look at the timings for each draw call / the number of cycles used by each shader (more info here)

You can also profile on Windows if you are also able to simulate your graphics pipeline in classic OpenGL in your Windows version, but this may not be a good idea as the iPhone's GPU is very different than a classic desktop GPU so the bottleneck might not be the same on Windows than on IOS.

To profile on Windows I would suggest using either Nvidia PerfKit (if you have a Nvidia card) or AMD's GPU PerfStudio if you have an AMD card.

There is also RenderDoc which is a nice tool but not sure if it provides much profiling information (it is more for debugging graphics issues than profiling)
