Whenever I try to do a performance analysis with Nsight on our OpenGL project, the GPU utilization shows nothing, although I can look at the API calls. The frame debugger is also working nicely without any issues. I’ve had the same issue in Nsight 5.3 as well. Our OpenGL application is still using the compatibility profile, but we have a special build that disables a bunch of legacy GL calls that aren’t supported and like I said the frame debugger does work. I’ve tried one of the Nvidia OpenGL examples and that one works without a problem, so I don’t think it’s my machine or my settings. Is there any way to figure out why Nsight was unable to collect that data?
Just to clarify, I’m talking about this here: http://i.imgur.com/p6XD0p6.png
