[SOLVED] NSight 5.0 Graphics Debugger GL

SOLUTION!!!
OK, I solved it. The reason why it does not display anything is that I switched my app to a 64-bit architecture a while back. Coincidentally, NOWHERE in the Nsight requirements is it mentioned that only 32-bit apps are supported. And since 5.0 is not supported on 32-bit operating systems, I automatically presumed it supports 64-bit apps (maybe only). To the Nsight team: If this is true, please update information accordingly.

I did a quick recompile, and a very simple WinAPI 64-bit app is not showing the in-window Nsight HUD. A WinAPI 32-bit app does work OK. So it is not related only to SDL, it appears the whole 64-bit architecture is a problem for Nsight.

So, switching back to 32-bit solved it for WinAPI as well as SDL, everything works OK now.

Original question:
Hi, I am pretty desperate, I cannot get the graphics debugger to start at all. I’ve tried everything apart from downgrading to Windows 8.

I have triple-checked if I meet all requirements for NSight. Here’s my configuration:
Intel Core i7-3770K, 16 GB RAM, ASUS P8Z77 Pro
Gigabyte GeForce GTX 680, 2GB RAM, driver version 358.50 (newest)
Win 10 Pro, fully updated, Visual Studio 2015 Community, Nsight 5.0.0.15294 (newest)

The requirements page is confusing, since in the table you mention that Graphics Shader Debugger is available on a single GPU system, but the bullet list below suggests that on a single GPU, only CUDA debugging is supported. Please explain what is actually correct. I am referring to this link: https://developer.nvidia.com/nsight-visual-studio-edition-requirements

Should I connect to the machine remotely, since it only has one GPU? Or should I enable the built-in Intel GPU (and connect my monitor to it) on the processor and use the NVIDIA GPU as a compute-only GPU. Does that even work with Graphics debugging, where you require it to output to a window?

On the same machine, with an older Nsight (I do not remember the version) and older system (Win 8), I was debugging Graphics just fine (it’s been over a year ago, maybe more). It was after seeing this video:

So I guess Visual Studio 2012 + Nsight 3.2 + Win 8 worked flawlessly. The HUD showed up after app start, and the Frame Debugger and Shader Debugger worked.

I am using SDL + OpenGL + GLSL + GLEW. There are a few GLSL compute shaders in my project, could these be causing the problem? I remember way back that Nsight showed a warning when I was using a feature that was not supported. Nothing like this happens now. I was using WinAPI before for window creation instead of SDL. Could this be the problem?

Starting Graphics Debugging shows no error, only displays the classic warning about TDR being only 2 seconds. And it does not complain about not being able to connect, so the Nsight Monitor is definitely getting the data.

Starting an OpenGL app that just clears the framebuffer does not work as well.

Please help me. Did I miss some configuration? I left all settings on default. My work goes much slower when I cannot do shader debugging and this would help me spare countless hours. Thank you.

OK, I solved it. The reason why it does not display anything is that I switched my app to a 64-bit architecture a while back. Coincidentally, NOWHERE in the Nsight requirements is it mentioned that only 32-bit apps are supported. And since 5.0 is not supported on 32-bit operating systems, I automatically presumed it supports 64-bit apps (maybe only). To the Nsight team: If this is true, please update information accordingly.

The other option is that only when using SDL this problem occurs. I will try to find out.

So, switching back to 32-bit solved it, everything works OK now.

I did a quick recompile, and a very simple WinAPI 64-bit app is not showing the in-window Nsight HUD. A WinAPI 32-bit app does work OK. So it is not related only to SDL, it appears the whole 64-bit architecture is a problem for Nsight.

Hi michalferko,

Nsight doesn’t support 32bit OS from Nsight 5.0, but do support 32bit app runs on 64bit OS and 64bit app runs on 64bit OS.

I am 100% sure Nsight support 64bit app, can you try to build this: https://github.com/Microsoft/DirectX-Graphics-Samples/tree/master/Samples/D3D12HelloWorld , this is Win10 DX12 sample codes, and it’s set to x64 target by default. It works fine on my 64bit OS with Nsight.

I am thinking there might be something else which bring the issue to you, could you confirm:
- your sample is a native c++ project? not a .Net managed project?
- do you compile all related libraries and external libraries to x64?
- can you run your x64 bit sample smoothly even without Nsight?

Thanks
An
