That’s good news. For debugging, you can use either PIX (see https://devblogs.microsoft.com/pix/pix-2306-21-preview/ for some information) or Nvidia NSight, which has support for work graphs (see Feature Enhancements): https://developer.nvidia.com/nsight-graphics-2023_4
This link has a bit more info on profiling and debugging of work graphs with NSight (under “Profiling and debugging tools”): https://developer.nvidia.com/blog/work-graphs-in-direct3d-12-a-case-study-of-deferred-shading/
