As the title notes… Rhino may not be seeing my 3080. Not sure what to do… thanks

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 GU…

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. Rhino 7 SR15 2022-2-8 (Rhino 7, 7.15.22039.13001, Git hash:master @ 2833e18992fc4b5cf99bb29c4d8e8add4f02074d) License type: Commercial, build 2022-02-08 License details: Cloud Zoo Windows 10.0.19042 SR0.0 or grea…

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

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…

Hi Kyle - thanks - just installed without doing this, & it still doesn’t show up. I’ll see if I can reinstall as you recommend. Standard graphics configuration. Primary display and OpenGL: NVIDIA GeForce RTX 3080 (NVidia) Memory: 10GB, Driver date: 1-28-2022 (M-D-Y). OpenGL Ver: 4.6.0 NVIDIA 511.…

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! -Jakob
