Rhino shift slow

Hi guys!

Just a quick one, does anyone know why my rhino file is super slow after doing anything when holding down ‘shift’ key, like to make a line straight or in grasshopper to add mutiple elements. It takes a lot longer than it usually does

Thanks!

Hi Jelena,

Please run SystemInfo in the Rhino command line and post the result. Thanks!

Let’s update your Nvidia driver first.

To further troubleshoot we can disable 3rd party plugins in File>Properties>Plugins

thank you!
what do i select when it says “select product category”?


hi! i did what you said and disabled vray for rhino however I now need it again and have tried to reinstall but this happens. pls help!

HI Jelena,

I don’t why the plugin isn’t loading. There is a dedicated forum for Vray that may have he answer.

@Jelena2 could you try the following:

Run _PluginManager
In that dialog click the Install… button
browse to:
C:\Program Files\Chaos Group\V-Ray\V-Ray for Rhinoceros\V8
double click VRayForRhino.rhp

I was having issues a while back getting to run Vray in Rhino 8 and that solved it for me.

i don’t have that file when i search:(

@Jelena2 what does this folder look like at your end?

i only have this



might completely delete it all and see if that works

yeah there is no VRay installation. You’ll need to reinstall it.

any chance you have a link?
what i did do was create a new free trial account install vray for rhino through chaos

chaos.com, then login and download the product

yeah ive done that, thank you for trying tho i appreciate it

if the above doesn’t help, then pls follow @Japhy 's suggestion and contact Chaos. @Nikolay might have ideas as well how to solve this.
