Move, Rotate and other commands very slow

Hi, I’m having issues with Rhino’s performance.
The PC has the latest soft and hardware.
The issue happens with a certain file.
Everything works perfect when I hide one specific mesh.

Hello- if you have an example file that shows the problem, please send to to my attention, along with a link back here in your comments.


I exported the file, if I open that file it works fine. I don’t know why…
