Rhino lagging after windows10 update

Hello, Rhino 6 is lagging since last night’s windows 10 update to the point I can’t work with it anymore :confused:

GPU is going into the red zone, so I have updated the NVIDIA driver as well as the Intel graphics card driver, but it doesn’t make a difference.

Any ideas where to go with this?

Here is the system info:

By the way, the element that is pushing the GPU into the red zone, is the Desktop Window Manager, however it only seems to be affected when Rhino is up and running. Website don’t load or lag while Rhino is running for instance, When I shut Rhino down, websites are fast again…

Hi Arman - can you try disabling VRay temporarily and see if that makes a difference? Options > Plug-ins page, uncheck the Enabled box then close and restart Rhino.

Also, please make sure to update the drivers from the Intel and
NVidia websites, do not rely on Windows to update correctly.

Hello Pascal,

For the time being things are stable. I shut the PC down and placed it for 20 minutes in the fridge since it was very hot (damn heatwave!). Even the thick glass panel it was placed on was hot!

Maybe the laptop just got overheated and that was the sole culprit.

I’ll see how it behaves the next hours. If issues arise again, I’ll try your suggestion!

NOOOOO!!! take it out of the fridge!! condensation in a computer is disaster!!

hot parts + cold air= condensation = dead computer.

just let it cool to room temp by shutting it down!!

true that! But luckily all is fine. It wasn’t in there for long and I didn’t cool it down to low temperatures. just to room temperature as I felt this would not be very good to shock the system’s parts…

Rather than start a new thread, I’m adding to this one as Pascals reference to disabling Vray proved very helpful.

I’ve been having laggins issues with the object snaps. Rhino is acting as if there is a rubber band connecting my mouse to the cursor and it’s hard to get accurate and quick snaps.

Per Pascal’s suggestion here I diabled Vray and the curosr lag is cpompletely gone. Not only that, Rhino 7 starts up near instantaneously as compared to the speed it takes with Vray.

Is there any workaround to this issue othere than leaving Vray deactivated unless it’s needed for rendering?


Hello - I would be sure to let VRay tech support know about your observations – if they know what to look for and can repeat it, then more likely they can do something about it.


Great, thanks for the quick reply. Will do.
