Depending on the display driver you’re using, you might need to set the environment variable `OPTIX_FORCE_DEPRECATED_LAUNCHER` to 1 to let the user defined OptiX device functions appear inside Nsight Compute. This is a temporary workaround and will be solved in the future.

Here also read especially the last bullet point about the line info and debugLevel setting which is important for profiling:
