"Unknown error" prevents me from inspecting the pipeline state for any draw or dispatch ca

I am having a strange problem with NSight: it does not show anything for any draw or dispatch call, accusing an “unknown error”.

All I want to do is to be able to access the pipeline state for some calls, as in here:


However, when I select the desired call and click on “see details”…

I get this:

I had a pretty complicated project, that I reduced to a simple shadow mapping application on DX11, and still nothing.

My specs:

  • Microsoft Visual Studio Professional 2010 version 10.0.30319.1 RTMRel
  • Microsoft .NET Framework Version 4.0.30319 RTMRel
  • Nsight version 3.2.2, build
  • nVidia GeFoce GTX 680, driver 331.82
  • Windows 7 Professional 64 bits (Service Pack 1)

Any help would be much appreciated.

Thx in advance,


Hi Tiago,

Sounds just like the issue that Florent in the other thread is reporting - just on a Win7 instead of Win8.1, sorry about that. If you have a reproducible application, do you mind PM me? We can check it out.


Thanks for your reply.

I am close to a deadline to a conference, so I won’t be able to do PM you before Monday (Tokyo time). Will do it for sure, though.



Just sent you a private message.

Thx in advance,
