When using Vulkan ray tracing pipeline on NVIDIA devices with HW ray-tracing cores (RT core), is there a way to obtain GPU hardware metrics or profiling information for the RT core - using Nsight Compute (or any other NVIDIA tool… the new Nsight Graphics perhaps?).
Any tips appreciated.
I believe Nsight Graphics would help with this. I will transfer this thread to that forum.
Hello,
Thank you for your question on which Nsight tool can be used to obtain profiling information for the RT Core. RtCore metrics are only available in Nsight Graphics Pro release. However, if your goal is to optimize ray tracing shaders, the Shader Profiler can provide equivalent or better details. In the shader profiler, you’ll see the source lines where the shader is either waiting for RTCORE to return intersection data, or when throttled by RTCORE (ray casting at a high rate), along with all other shader stall reasons.
Regards,
OK so how do I get the Pro release?
Hello,
In order to get the Pro version of Nsight Graphics your company would need to have a signed Non-Disclosure Agreement with Nvidia. Sorry for any confusion this may have caused.
