Great!

I hope there will be some kind of improvement soon!

I did the system check, maybe it is of some help:

I also did just a fast test now.
Maybe this can also help to pinpoint the origin of the slowdown:

  1. I created a new file with standard Rhino 8 template (small, Millimeters).
  2. I created a lots of Layers and Sub-Layers. Not much of a slowdown… but not snappy as Rhino 7…).
  3. I created a Sphere and deformed it with a cage command an LOTS of subdivisions! 700MB FIle.
    Orbiting with control points activated was very slow… but Layer colapsing and uncolapsing is not very fast, but not as slow as happens with my own files.
  4. I opened the same file in Rhino 7 and Layers behaves snappy as usual.

By now I think the slowdown in Rhino 8 may happen with files created in Rhino 7.

In fact, I just imported some geometry from my current project (done in Rhino 7) and now layers colaps much slower!

Up to some seconds… so quite annoying… :expressionless:

I hope this helps!

Hi @mirkos,

The slow down between V7 and V8 is due to the change in UI library and has nothing to do with the 3dm files coming from V7.

– Dale

strangely, as I described, a quiet heavy V8 file with lots of layers showed a big slowdown just after I imported geometry from Rhino 7…
I went from microseconds to 1-3 seconds each time I clicked on the colaps triangle

If you can’t replicate that, then it was may be just casual… I don’t know, but it was what I observed yesterday.

Anyways… whatever the reason is, I hope there will be a solution soon.

Right now I’m back to Rhino 7. :expressionless:
I just need a snappy interface for my everyday work.

I have recorded some videos showing what I experience.

Rhino interface (you can see how I can move my mouse around and Rhino is still adding layers, its a slow Rhino :face_with_hand_over_mouth: :rhinoceros:)

Interface working as expected. (notice how much faster and smooth it looks, it also feels that way)

I think Dale is looking into this.

Please fix this, very disruptive to workflow. Returning to V7.

Hey everyone, thanks for your feedback on this issue.

There have been some performance improvements of the Layers panel in 8.9 (the current Service Release Candidate), so please give it a try. That being said, we still need to get this going faster and is still on our list.

I can see a small improvement in the time it takes to create a layer. For my workflow still too slow compared to past Rhino versions, but it’s good to see there is progress.

Also panning in the viewport looks faster.

Hi guys,

Experiencing the same issue as stated above, unfortunately to the degree that I just rolled back to R7. It’s very disruptive to the workflow, simply can’t use R8.
