Render settings question

I recently got a new computer and imported my rhino options and render settings. However, I am getting very different looking viewports despite seemingly replacing the settings. Ambient Occlusion, which worked nicely on my old computer is now rendering with very harsh shadows. Does anybody know what the problem might be? See attached pictures

can you post a file for us to take a peek at?

or a part of a file that shows the issue?

if it’s confidential, email it to tech@mcneel.com

I just emailed the file. Thank you!
