As the title notes… Rhino may not be seeing my 3080. Not sure what to do…
thanks
Hi @Andrew_Turner
Start by opening Rhino and run the SystemInfo command, then copy/paste the resulting text in a post here - that might give people a clue about what’s going on.
HTH, Jakob
Hi Jakob-
Thanks. Here’s the system info & what I see when I select the CUDA tab.

Hi @Andrew_Turner
Start by updating your driver - that’s the most likely reason, especially if it’s more than a few months old. Keeping both Windows and Nvidia drivers updated are key to keeping Rhino happy; especially if Windows auto-updates, as those updates have a tendency to break things

Will do.
Generally, when things are working ok, I don’t like updating drivers!
I’ll try it out here, though. Should I see it show up as a CUDA render device after updating?
thanks
If not, it’s one for the bigger brains - @nathanletwory

when you update, do a clean install by choosing the custom install option then checking the “clean install” check box- leave everything else as default.
( I recommend doing this for all nvidia driver installs)
then I personally always set my nvidia control panel as shown-
@jeff may call me out as this being nonsense, (and thanks in advance for the lesson if so) but it’s what I always use with good result.

Hi Kyle - thanks - just installed without doing this, & it still doesn’t show up. I’ll see if I can reinstall as you recommend.

Still nothing showing under CUDA after trying clean install per @theoutside … going to try another restart & see what happens.
Hi @Andrew_Turner
You could try and disable the Datasmith plugin from the pluginmanager and restart Rhino. Sometimes plugins interfere in the weirdest ways!

Uh… ok - been using that pretty heavily this morning. 
Not sure that it would affect a display driver, but I’ll try it just to see.
Me neither, but sometimes weird things happen inside computers

if you go to tools>options>view>open gl
does your card show up there?
Any chance your renderer is not set to rhino render?

Try running the command RhinoCyclesEnableGpu. It may be that during one start of Rhino in the past initializing of CUDA devices failed. This then was captured during initialization and GPUs were disabled to ensure Rhino keeps on starting.
I probably should show somewhere in that device selection GUI that this has happened.
addendum: RH-67521 Notify user in Device Selection GUI that GPUs have been disabled

Hi Kyle - here’s the card; I am set to Rhino Render.
Hey Nathan - this worked.
