At the moment all the tool tips for columns in source view etc just reiterate the column heading text. More descriptive text including noting opportunities for performance advice, or what is good/bad there would be great.
Thanks for the feedback. We will improve tool tips text for our next release.
Please refer the https://docs.nvidia.com/nsight-compute/NsightCompute/index.html#profiler-report-source-page section in the Nsight Compute document for a description of some of the metrics shown in the source view.
