Hi frv,
thanks for sharing.
Did you render the same scene on an intel Mac too?
The ray total# seems very low for this kind of scene. Doesn’t look like the mats are overly complex, and the rays/sample look normal.
Would be interested to see a Intel Mac comparison of this scene, if possible.
Maybe it's time to update the corona benchmark tool.
The M1 max in the result list shows similar rays/s that a i7-8700K got in 2018.
Not sure if this is a real comparison if the benchmark runs in rosetta.
