Rhino render issue loading CUDA Kernel

[lance_hazelton]

Hi Rhino team, I just upgraded today and am getting the following warning when I try render.
The warning that comes up in rhino 8 when I try to start a render is

Failed to load CUDA kernel from C:\Program files\rhino8\plug-in\RhinoCycles\lib/kernel_sm_61.cubin’(invalid kernel image)

My graphics situation is as

Hybrid graphics configuration.
Primary display: Intel(R) UHD Graphics 620 (Intel) Memory: 1GB, Driver date: 1-22-2022 (M-D-Y).
> Integrated graphics device with 3 adapter port(s)
- Windows Main Display is laptop’s integrated screen or built-in port
Primary OpenGL: NVIDIA GeForce GTX 1060 (NVidia) Memory: 6GB, Driver date: 1-22-2021 (M-D-Y). OpenGL Ver: 4.6.0 NVIDIA 461.40

Thank you for you help

Hey @lance_hazelton !

Try updating the Nvidia driver for the GTX 1060. Any luck?

Don’t worry, you’re not alone - this has happened more:

Rhino8 WIP Cycles rendering "flat" or not rendering

Hi @can.aysan I’d start by updateing that driver - that’s almost 2 ½ years old. I that doesn’t do the trick, you might try the Repair option in the installer (Go to Windows Settings>Apps>Find Rhino in the list, the click Modify and choose Repair) [image] HTH, Jakob PS Note that the Cycles kernel might take some time to compile the first time you run it - this is normal

Failed to load cuda

Often Windows updates appear to mess up drivers. It is good practice to do a clean install of drivers after a Windows update, especially a bigger one.

Raytracing CUDA kernel error

Hi Nikolai, install the latest NVidia-driver, then it should render. Here more details: Cheers Michael
