Sam thank you so much for your detailed and thorough response. I still have a lot to learn about computers and it’s been difficult to figure out. You explain it very clearly though and that’s very helpful.
I opened your file in my PC as is, did a quick pan and zoom and did not notice your lag . Here is what I see:
Hi Rod, difference in viewports can possibly be caused by using ‘clipping mask’ function in Layout and scaling it after clipping it. This will quickly degrade the quality. So make sure there aren’t any clipped viewports.
Similar to what I saw. Seemed to be little to no issues in pan and zoom.
