Rhino 8 is frustratingly slow

Rhino Rhino for Windows
1

Hi,

I am sorry to ask but - what is going on with Rhino 8?

We have tried many different files now, on different computers here in our office and also privately at home and tested Rhino 7 vs 8 under the same conditions. The result is the same when testing max speed. Rhino 8 is always slower than 7, often up to 50 percent which is something you can definitely feel when working. Rhino 8 takes so much longer when doing things like deleting layers, isolating, copy pasting or just navigating the viewport - especially with complex models.
All of my colleagues experience the same issue and many of them don´t even bother working in Rhino 8 anymore but just keep things in Rhino 7.
The issue is not in the file or the setup. We have tried the latest patches, the latest graphics drivers.

Is the developer team aware of this? Is this something that is being worked on?

Hej Adrian -

Nothing specific that I know of, no.
Please run the Rhino SystemInfo command and copy-paste the output here.

Thanks for the fast reply Wim. It just seems to me that this is an issue that many people are having, even reading here on the forum? I can´t imagine that it has anything to do anything with the systems used. If you are testing a complex rhino model, are you getting the same speeds as rhino 7?

Any benchmarking we do is sans plugins.

I have had problems with long delays as well. The worst was 60 seconds (or more) when copying and pasting very simple geometry. This was awkward and frustrating when doing a class demo; I got really good at tap dancing.

SR 16 and 17 seem to have solved it. (I filed a bug report at the time.) I always wonder if the bug was fixed purposely or accidentally. :grin::+1:

Looking at the resolved youtracks for the last couple months it was not accidental. There are a number of improvements and bugfixes with the word slow (one directly related to copy paste)

7

Ok, very good to know. I never heard if the problem was specifically identified and solved. It was more like, “So … does it work OK now?”

Just happy it stopped!

i have the exact same issue here, please fix asap! Our firm upgraded from R7 to R8 earlier, but I am still using R7 because of this. there’s a noticable lag between 7 & 8 when working on the same rhino file. and is not just me, i asked everyone in my team they all notice the same speed difference. I definitely dont want rhino to become as laggy as autocad…

Hi eye -

Could you describe that issue in some detail?

When troubleshooting an issue, please disable all 3rd party plug-ins in the Plugin Manager and restart Rhino.
-wim

A post was split to a new topic: Block Issues

12

You’ve posted nothing about these issues you claim to have, how do you expect them to get fixed? And they have the best chance of being fixed if you’re running the current version if not in fact the WIP, which is the best part of using Rhino.

13

Yep. Everything is slower by a lot… Also c# editor is WAY slower to just open, no comparison with 7. Then using it… a bad joke.

What fears me is that once again they stopped fixing things and are pushing everything to 9… so I expect we will not see again the speeds of 7/6/5… :frowning:

It’s simply not.

Lucky you. It is for me.
And I spent (wasted?) a very lot of time trying to report in detail… I don’t know what else to do if not suffer and post my comment where I suspect it matters.
Even simply rotating the camera is slower (3d mouse) , the UI still kills the performance of the viewports. Subtle, but it’s worse than on 7. And I managed to see this while using 99.9% of my time Rhino 7.
I open Rhino 8 for minutes and leave it horrified every time. Every. Time.

Samples are always welcome as there are many variables that can effect this.

  1. Can you send us the results of the SystemInfo command in Rhino?
  2. Also, if possible the file would be great to take a look at. Large files can be sent here to us: Rhino Accounts

In Rhino WIP we have new tools to look at files. I can run it and see what might be causing the slowdowns.

18

Sure, dealing with this in a less public way, we can move this to support@mcneel.com and work thru the issues.

I can take you through all the possible ways we test it. This just takes a lot of back and forth as we brake down were the slowdown could be.

You are correct, this is not uncommon. The problem is that there are many different things that can cause it.

A newer tools we are working on to find the issues quicker is this: Rhino WIP Feature: New Audit3dmFile…Graphically

@Durdona_Qurbonova

what problem?

Does grasshopper not start at all? Maybe share a short screen recording of what you are seeing.

In any case, your display drivers are quite old, so it would be good to update these to the latest drivers that are available first.
