Doubt about CPU performance

Hi everyone,

I have a question regarding the profiler, more specifically about the CPU Camera Render.
When the value of time(ms) of this function in a frame is 0, this is because it is waiting for the GPU to perform calculations or it is because the CPU is not being used. If so,why wouldn’t the CPU be working on that frame, if it still has to render the scene?

Uh… I’ve not seen that happening yet… Are you using On-Demand Rendering? Is this with Built-in render pipeline or URP/HDRP? Is there any cost to Rendering on the Render thread? Could you maybe post a screenshot of this in Hierarchy view and Timeline view?

Generally speaking, rendering on the CPU is about gathering all the info about what needs to be drawn with which shaders and parameters, to then be passed to the GPU for the actual drawing. So if something is displayed the CPU cost could be low or offloaded to the Render thread somewhat, but non existent sounds curious…
