If you develop in Visual Studio 2013 and 2015 versions, you can use their GPU Usage tool:

Screenshot from MSDN:
Moreover, it seems you can diagnose any application with it, not only Visual Studio Projects:
In addition to Visual Studio projects you can also collect GPU usage data on any loose .exe applications that you have sitting around. Just open the executable as a solution in Visual Studio and then start up a diagnostics session and you can target it with GPU usage. This way if you are using some type of engine or alternative development environment you can still collect data on it as long as you end up with an executable.
