Which part of the code are running in RHI thread, rendering thread and game thread?

Hi,

I am currently working on optimize the CPU performance for RHI thread, rendering thread and game thread.

I wonder what procedures should I do, in order to find which part of the source code are running in each of these three threads?

Best wishes,
