Rhino 7 is laggy in viewport

No matter what kind of file im working with, my rhino 7 is laggy while rotating or zooming. its perfeectly fine in rhino 6 whith the same models. any help?

The NVidia settings used to swtich the GPU, but now Windows is. Is it being done correctly? Under Window Setting Graphics Settings, you should see something like this, though it might be using light colors.

(I have the other setting off for battery life, but I should research that more.)

Yes, that’s the same as yours.

and my graphic card is a good one. It’s a Quadro 3000. which should work even better.

I also have a Quadro A3000/Notebook. It’s been working pretty well for me, under Cycles, too. Though, it only has 6GB of memory. For very large projects that might be an issue.

Could it be that processor performance is turned down. If it’s a laptop, is the computer getting hot?
Is it V-Ray’s preview, or Rhino?

Obviously, must to have enough memory, or the computer will use into virtual memory, but if you have enough memory, adding more will not help.

In an already saved and backed up, saved file, you can open up the task manager using [CTRL][ALT][DEL] once, and then chose Task Manager. From there, you can check memory usage. The GPU usage will be low, because it only works for DirectX. You can select Logical Cores, in the CPU window to see which each core/thread is doing. There is a Kernal Time option, too.

I use Open Hardware Monitor, and set widgets on my desktop to keep it all in view.

I believe that even if Window now handle the Optimus-style switching, the nVidia applet still finely controls the GPU, and the settings may be set high for other things, there. You can make a custom Rhino profile in the nVidia app, and make sure the GPU settings are all reasonable and good for Rhino.

In the screenshot below, please notice that I made a custom profile for Rhino. Whenever Rhino starts, it should still apply these settings.

Your settings AA seem moderate, ok: Anti-alias mode: 4x
But, if you have a 4K 15" laptop, this can be lowered, perhaps to 2x : )

Currently, you have: Anisotropic Filtering Mode: High
Unless you are using a lot of high-res textures, looking down long hallways and streets, this can be set to lower anisotropic filtering here, or turn it off when you are only modeling shapes:

Generally, you don’t want many triple buffering and pre-rendered frames. This will prevent your GPU from cooling–before you move. It’s useless during translations and turning the view, if it the GPU cannpt guess what your next move would be.

In the nVidia settings, there is a low latency mode. That’s a keeper.

Power Management. Please watch your laptop cooling!

The shader cache is a silly waste of SDD endurance/wear.

The maximum Framerate can be set the what your monitor does. I would keep it at 60FPS. Why? Because it’s not about the ensuring the fastest frame–but preventing the slowest. Let the GPU cool whenever it can.

The texture filtering is something also to check. Not a lot of savings, but a penny here, a penny there.

Vertical Sync is nice, but it costs framerate unless you have Freesync, or whathaveyou. There used to be adoptive options, but not any more.

Threaded optimization should be on. It would probably guess this, but what the heck.

Also, a cool laptop is a happy laptop. Putting something safe and small under to lift it for more are is good, but I don’t recommend non-factory fan cooling pads because if the airflow goes the wrong way, it will stall the air inside the laptop. Even a upsidedown mesh letter tray will cool it, also long as the laptop is stable and secure.

For my P15-Gen2, I put some cooling lifts on Thingiverse. They were made with this program called Rhino 3D. Perhaps you have heard of it. : )

Other things you can do to prevent latency:
Use lightweight extrusions whenever possible.
Lower your system-wide meshing setting.
Use Blocks for objects whenever possible when doing large projects.

Let’s try something…

  1. In Rhino Options > Plug-ins, change the list filter at the top to ‘Plug-ins that do not ship with Rhino’
  2. Disable all of them
  3. Close and restart Rhino

Does the problem go away?
If yes, systematically enable the plug-ins one at a time, restart, and isolate which one is cause the slowness.

Can you identify a plug-in that is causing the problem?

I’m having this same issue. I just tried this and it didn’t work for me. It only happens in rhino 7. It gets laggy and shows weird shadows on shaded view.

Rhino also prompt me to update my nvidia driver, I know my geforce gt 720 is not a power house, but i’ve never had this problem before in rhino 6.

That’s a pretty old GPU (2014) with less than minimum VRAM, and an old driver.

See if this driver update helps:

It might be time for a new GPU or system if the whole setup is as old as the GPU.

Updated to this driver. The problem keeps. Lags and shadow glitching.

I assume you’re not running multiple monitors?
You could also try turning off GPU Tessellation:

It probably means replacing your old system with one that has the power to do what you need.

It’s also possible there are problems in that one file that are causing a bigger resource demand.
If it’s only this file that has problems, and other similar files don’t, then that could be it.

See if the SelBadObjects command select anything.
If it does then ExtracBadSrf can help you fix up the problems.

I’m using two monitors. I tried this and it didn’t solve it. I just re-installed Rhino 7 and nothing. It’s weird because now i’m testing rhino WIP and shaded view doesn’t show this strange shadows (though rendered/artic view are laggy, but i think this is due to shadow quality memory :slightly_smiling_face:, so no biggy there).

Rhino wip

Rhino 7

I’m most worried about shaded view because it’s a basic and not taxing view style for modeling.

Is there a way to download past versions of rhino 7?

I’ve tested different files and it’s not that. But, now that we’re here, I’ve seen this bug before where the rendered view of a file has a similar one side shadow that moves with your camera when you open a file directly from a dwg, 3ds or non rhino related formats. I always end up copying and moving the objects to another clean new file and this to fix it, which I originally thought was the problem with this thing, but then I figured that it wasn’t rendered view, but shaded view the one with this problem.


It got fixed! So apparently activating shadows on shaded view does that.??
I just decided to default everything on shaded view.

shadows off

shadows on

Maybe something to check out.
