Debug DX11 Frames with Nvidia Nsight

UPDATE: There is also a similar tool that is open source, see this blog post: debug-dx11-frames-with-renderdoc

Just a quick one found today and everyone should know about. Nvidia Nsight Graphics works just fine with vvvv and dx11. This can help to profile your graphics performance and find bottlenecks.

The steps are pretty simple:

  • Start the application, click "Quick Launch" and you should see this screen:
  • Add your vvvv.exe and press "Launch"
  • Load any patch/scene with dx11 and you should see some Nvidia HUD in the renderer
  • Press CTRL+Z and then SPACE to capture the latest frame and bring up Nsight
  • Now you can inspect your frame like this:
  • Or have more details, timeline, API calls, timings etc. in the Nsight application:

That's it, just so you know.
Yours, devvvvs

oh nice! same goes for renderdoc. And I also like to point out dotTrace and dotMemory by Jetbrains. with dotMemory you can have a look which object takes up how much space in ram. We're currently using that to hunt down a memoryleak. And with dotTrace you can have a look at how long methods are executing and a timeline about what each thread created from vvvv are doing ;)
unfortunately though they're not free

And for general application profiling of .Net/Windows: PerfView (Perfview on Github)

@microdee and @beyon thanks for the (open source) additions! didn't know about them except the jetBrains stuff.

Just came across another free .Net profiler: CodeTrack

Have just had a quick look at the web site though so don't know how it compares with the others.

@beyon that looks quite nice also. i'll try that one as well in our latest project.
