Rhino 6 running slow

Having the exact same issue. Same software version, no plug ins that do not ship with Rhino. I thought it may be RhinoCAM2019 causing the issue, so I uninstalled it, and still have the same problem. This is a new issue and I’m wondering if the current SW version is the culprit. Is there any way to reinstall the previous version?

Here’s my system info:

@jsullysix
No, your slowness is because you’re running a barely supported Intel 4000 adapter with an embarrassingly old driver.

Install this driver from 10 January, and go shopping for a computer that meets Rhino’s System Requirements.

Any better?

…except that I’ve been using Rhino 6 on this laptop without issue for months. The only thing on it is Rhino, and I only use this because RhinoCAM isn’t Mac compatible.

Again, everything was fine until the most recent update. I’m happy to install the driver you shard (and thank you for doing so), but there has to be another contributor to the issue.

Is it possible to install the previous software version?

The change is most likely something that changed in Windows. This is what triggered the need for the driver update.
Going back to an earlier build of Rhino does not fix it.
We’ve tried multiple times at user’s insistence.

If this is still slow after the driver update, we can disable Rhino’s use of the driver and get it back to the earlier performance, but that disables a few other V6 display features.

It really is time to replace your old computer.
What is it, 7 or 8 years old?

Unfortunately, it did not fix it. Any other idea of what could be happening?

Thankfully, the driver update handled my issue. Thank you for the link.

Finally, while I’m aware of how old this laptop is, I use it solely to create basic 2D - 2.5D toolpaths, and it’s done what I’ve needed it to. I bought it refurbed for cheap based on the recommendation of a friend who is in my industry and knew what I’d be using this little doorstop for. All of the main work is done on my mac. Rest easy knowing that it’s new.

Good luck to the OP, I hope that your issue is resolved soon.

Hi Rania -

Do you know what has happened on your system between the time that it worked fine and when it started freezing? A Windows update, new hardware, new software, new Rhino version, new plug-in?

Is this also in a completely new file from a factory-default template?

Could you please post the SystemInfo once more but now the complete output in one go?
Thanks,
-wim

The only updates have been Window updates - nothing else that i can remember.

Sure:

Did you try disabling both Thea plug-ins, and restart Rhino?

I did, unfortunately that didnt fix it.

That’s really odd.

One other thing to try…
Disconnect one of your monitors, start Windows, and start Rhino.
Then does it run faster again?

I am assuming that you are not running multiple concurrent Rhino sessions as well.

John, it seems like the issue is gone. I think it was a prompted Windows update while shutting down the PC and now today Rhino is working fine.

Thanks again for your help.

Yes, restarting your computer has always been a front line problem solving tool, and anyone can do it.
It’s so common, I don’t often think to suggest it as I know everyone knows.

I’m glad you’re sorted.

Awkward is Rhino tells that my driver is:
Driver date: 1-29-2020 (M-D-Y). OpenGL Ver: 4.6.0 NVIDIA 442.19

And Nvidia reports:

Hello - and, with only one instance of Rhino running, if you block Vray in Options > Plug-ins and then close and restart Rhino, is there any change?

-Pascal

No changes at all.
In fact, i am working in a file of a block apartment buildings. 192 MB size file. In desktop SSD, saving file is like 40secs / 1min. It took alf of the time at my Work with less machine performance and HDD

At Office we have Rhino 5 working on NAS server and low machine specs then mine here at home. At office we work aith large files and extreme master plans with a lots of external block links. Al those works are opens and saves from NAS HDD and i can argue that Rhino 5 is somehow more fast.
Its fast open. Its fast in close. Its fast on block manager compared with Rhino 6.
Now i made a update from Rhino 6 SR21 to Rhino 6 SR23. I notice a small improved in command line, and simple workflow like copy, past, extrudes, booleans and trims.
Although still slow in change display modes, slow in open files from SSD, save files, open block links. Sometimes rotate viewport stuck small seconds.
I have a good machine - AMD 3950X and RTX 2080ti. all stable drivers installed.

PS: Perhaps is due the fact that this file was crated in Rhino 5 and keept working on Rhino 6?

What happen to the smoothness of work in Rhino?
How is that command line to test speed viewport?? i can not remmember right now?!!!
Any suggestions?
Cheers

Hello - can you, as a test,
-SaveAs _SavePlugInData=No
a copy of your file and see if the copy behaves any better?

-Pascal

going to test. give me a minute

still saving…

Ok. lets have some conclusions.
Open a file (save plugin data = no) - took about 4.91 sec. (SSD save)
Save As (save plugin data=no / save textures=no) - took about 38.48sec (ssd save)
It was better then with save plugin data=yes / save textures=yes). But still slow for this kind of file and SSD disk

Real Pain, need waiting for save and open files. What happen with Rhino 6 versions?

I have noticed that when create a fresh file in Rhino 6 this slowing downs does not happens like when imported Rhino5 into Rhino 6. If we strart from scratch a new file in Rhino 6 it will run fine.

Noticed to disable vray 4.10 from Rhino 6, rhino became super fast. Start boot is like 1 second. Incredible :slight_smile:

But wow can we have it fast with vray enable? We need to make realistic renders

Cheers
