Rhino runs very slow!

A post was split to a new topic: Slow getting grafical functions after clicking on the icons

Hi Muhammet -

Thanks again!
When I open that DWG file in Rhino and run SelDup, I get the following:

Found 768 duplicates. 1 point, 767 curves added to selection.

In that file, zooming to extents shows this:

When I open the 3dm file that you sent us, however, I get this:

Found 77810 duplicates. 623 block instances, 12 points, 75708 curves, 112 surfaces, 750 texts, 605 hatches added to selection.

And zooming to extents shows this:

Apparently, the file that you are testing in Rhino is not quite the same as what you are using in AutoCAD… Is that something that you can confirm?

It’s absolutely true, I tried the same way after you. I imported the DWG from scratch and the file became much easier. I don’t understand why the first file is copied so often. Thank you very much. For me I need to spend more time with Rhino.

Not seeing much of speed difference.

I think the reason why AutoCAD feels faster is because I triggers “Adaptive Degradation” when a certain % of the objects are hidden while transforming objects. in both AutoCAD and Rhino tests, neither my GPU or CPU was fully utilized, most of the utilization came from OBS capturing the screen in the background

I tried to find out if a certain object type could be the cause.
Apparently that’s not the case.

Make a new model and paste:

_Circle 0,0,0 1
_SelAll
_Array 320 320 1 3 3 _Enter
_Zoom _Extents

Results in ~100000 objects.
Or try a point instead of a circle.

Display speed is fine.
When it comes to _Move or _Copy I see the performance drop.

I assume it has nothing to do with the display.
