Rhino 7 runs slow and is stucking during moving or zooming an object

Hi everyone. As the title said I have problem with my Rhino 7. It runs slow, stucks very often even when the opened file is small (8 MB) and when I want to work with a larger file (500 MB) it freezes and after a while is not responding.
I was searching on forum and finding some possible solving errors from others that have similar problems. Than I tried recommended steps, with hope it can fix it but nothing helps.
For example I tried to run Rhino in Safe Mode to see if there are problems with Plug-ins, set on Document Properties>Mesh to Jagged and faster, I have the newest actualizations of graphics card, and one of the last tries was uninstall Rhino and then install it again.

Here is the System Information from my Rhino 7:

How does rhino behave with just a blank file, no geometry? Start with a new file, no template, should have zero items in it, no layouts, nothing!

if no problems, start adding simple things like some curves and then some extrusions or boxes or spheres. Does the problem start up with more geometry added?

Keep adding complexity to your file until the problems start popping up.
In essence we want to boil down all the possibilities quickly and see what is sparking the first issue of slowness or freezing.

I don’t have any more solutions right now, I’m just trying to help you troubleshoot.

Is your laptop running other things fine? Laptops are notorious for not running at full CPU speed without certain things being setup. My old laptop for example has to be run with a manual cpu booster or it always defaults to slow power mode and everything is slow…

To check this: go to taskmanager and performance and confirm your cpu is running at the speed you think it should be. Any thing worth it made in past few years should be running at least 2.5 to 4GHZ. We want to make sure you are not stuck at 1 or 1.5GHZ which might allow other things to run fine but could start slowing down your rhino for certain operations.

btw, your RTX driver is about a year old, might not hurt to update that.

The problem begins when I start creating a cube or sphere in a new Rhino file.

I have my laptop new, for a few weeks, so I will check what you mentioned.

oh i dont like seeing that your primary display is set to your intel integrated… that could be your problem right there!

google how to make your primary graphics be run by your RTX. Its usually an NVIDIA control panel setting.

this is what we want for max graphics performance:

Standard graphics configuration.
Primary display and OpenGL: NVIDIA RTX A4000 (NVidia) Memory: 16GB, Driver date: 1-18-2024 (M-D-Y). OpenGL Ver: 4.6.0 NVIDIA 551.23
> Accelerated graphics device with 4 adapter port(s)
- Windows Main Display attached to adapter port #0

Secondary graphics devices.
Intel(R) UHD Graphics 770 (Intel) Memory: 1GB, Driver date: 7-24-2023 (M-D-Y).
> Integrated graphics device with 4 adapter port(s)
- There are no monitors attached to this device!

About the CPU… I have to say that I’m not an expert, so please be patient… :smiley:
But I can say, that when Rhino is on, the CPU is running about 1.5 to 2.5 GHz. And the base speed (?) of CPU is 2.2 GHz

see above, i think your primary graphics is the issue…

So I tried my best and got this… but it doesn’t help

I opened some files and sometimes it turns slow in every type of display mode and sometimes it was slow only in “Rendered”.

Good you got the primary switched over nonetheless! and a new driver, great!

What happens when you go to wireframe display mode?
Is everything slow? When you draw a circle, is that slow?
What about extruding a curve, or making a subd sphere?
Are all operations slow?

I am currently out of ideas on what else the issue might be. Someone else on the forum might have some ideas.

Normally Rhino is one of the lowest overhead cad programs out there, able to run on old and slow machines with minimal issues.

Maybe run some pc benchmarking test on your laptop to see if you can flag a possible hardware issue, and try running some other programs to see how your machine behaves. ie: download the free meshmixer and run a makesolid on the test bunny or other mesh and see what happens.

10

Aah, yes, it is slow in Wireframe display mode too. And I tested these operations in one of my older (not that large) files and also in a completely new one.

I wiI will download the meshmixer and see what happens.

And thank you very much for helping me

Meshmixer runs without any problems, it’s fast and smooth.
I also run a benchmark test, some GPU stress test, few times and score was low, about 140, but it didnť write me any errors. Is this one of the possible causes that make rhino runs slow?

12

@John_Brock any insights here?
Their gpu might be on the slower side but doesn’t seem like the immediate cause for rhino slowness.

@Kateřina are you able to do a video screen recording that will show us just how slow your Rhino is behaving? It will help us get on the same page with relative comparisons. For all we know your slow is our fast! :slight_smile:

Meshmixer can really tax the cpu and gpu, if that is running smoothly then perhaps there is something wrong with the way your rhino is set up.

Bear in mind this is difficult for us to troubleshoot via forum messages, at some point you might need someone to assist you in RL or over remote on your computer.

It might also be time to post the full specs of your computer here.
cpu model and base speed:
ram make and speed:
storage type and size/free space:
Is rhino installed in default C:programs directory?

Your benchmark of 140 doesn’t mean anything to us without some kind of comparison # of what other typical GPUs are scoring with the benchmark software you used. If all other typical current gpus are scoring much higher then indeed your GPU might be a bottleneck.

Here is a video screen of Rhino, when it is new file and then I opened 29 MB file. The video shows it more slower than in real life… I sent also a screen video of task manager. I recordered it one by one but I did the same things, so you can see reactions of my laptop.

Also I want to mention that yesterday I downloaded Blender, to try if it is also without any problems like Meshmixer and there was the same problem as Rhino have, it is slow and stucking and even when I move or zoom on a cube, the NVIDIA GPU imediately increases to 100% and program starst to get slow.
