Volumetric Scatter affected (Same file, different computers) CPU vs GPU I've worked on a scene on my 2015 MacBook Pro and it looks great, but takes too long to render.

I bought an RTX 2080 for my PC and the volumetric scatter is barely visible.

Why is my RTX 2080 performing worse than my 4+ year old laptop and how can I get the volumetric scatter to show correctly?

EDIT 1

So I found one problem. For some reason all the light sources are reset to default values at 100w.

Changing the values to the values I initially had set them to does not make a difference.

HOWEVER

Now when I switch to CPU rendering the image is displayed correctly.
But GPU rendering still renders incorrectly.

EDIT 2

I've narrowed it down to CPU vs GPU.
When rendered on the CPU it looks exactly as I expect, but on the GPU it doesn't look right.
Problem solved by changing sampling integrator to Branched Path Tracing.

This is not needed when rendering on the CPU, but apparently required when rendering on the CPU.

I found the solution here: Volumetric scatter shader does not show light focused through lens correctly
