Why on earth is Visual Studio 2013 not supported by NSight ?
Who even uses earlier versions of Visual Studio these days ?
If the trending is the same it should be out by the next minor release of CUDA 6… if the feature is so important to you, register for the CUDA developer program and submit a request for enhancement (RFE) to support Visual Studio 2013:

Forum posts will not do much, I’m afraid.
