I had purchased a GeForce 680 so I can debug shaders in OpenGL as it had the ability to insert breakpoints in shaders and I was using that with Visual Studio 2017 and Nsight ver. 5.6 and it was working fine. Now when I went back to that system it is not working and the Nsight menu in Visual studio had disappeared . I tried using the stanalone Nsight to no avail. Although I did not upgrade anything in the system I can not figure out why it changed. Anyone knows how to debug shaders in old or new Nsight versions? I am not able to pay the big bucks to get a Quadro that is why I bought the 680 cause they had the ability to do that. Thanks
