Numerous online resources claim it is possible to debug OpenGL shaders using NVIDIA Nsight Visual Studio Edition. Here is an old video of it being done.
However, the Nsight VSE page mentions "the integrated Graphics Frame Debuggers and integrated Profilers have been removed" and I have been unable to find a way to add breakpoints to Shaders/Programs in the NVIDIA Nsight Graphics - Frame Debugger (the standalone replacement for the integrated version). I can view the shader code and even edit it, but not add a breakpoint. Is this still possible in any way from within Nsight Graphics or some other program?
Possibly even an old install?
