Counter mismatch between RGP & GPUProfileAPI

Open type-shangshu opened this issue 3 months ago • 0 comments

Hello, I am now trying to profile a ray tracing program on 9070XT, DirectX12. I capture some RGP reports and also try GPUProfileAPI, but sadly they produce different results.

  1. for execution duration, the reported time by RGP is slightly longer.
  2. for ray triangle test and ray box test, the reported results from RGP and GPA are completely different for the same  application and the same frame.
  3. I also notice that one ray tracing dispatch call can be split into 1 major dispatch + several small dispatch in RGP. Could this be the reason of my issue?
