Hi, I’m having an issue where Rhino Render (Cycles) only shows CPU in the device list and won’t use my GPU.
System:
Rhino 8 SR32 (8.32.26160.13001)
Windows 11
NVIDIA GeForce RTX 5070 Ti (Desktop, 16GB VRAM)
Driver: 610.62 (June 11 2026)
64GB RAM
What I’ve tried:
Updated to latest NVIDIA Studio Driver (610.62)
Set Rhino.exe to High Performance GPU in Windows Graphics Settings
Rhino’s System Information correctly identifies the 5070 Ti
What happens:
The Rhino Render device settings only shows a CPU tab — no CUDA or OptiX tabs appear at all. CPU usage hits 97% during renders while GPU sits at 2%.
I saw a similar report from a laptop 5070 Ti user (nilceros) where it was assigned to Lars. Is this the same issue affecting desktop cards? Is there a fix or workaround in progress?
surely there has to be right?
Thanks Guys!
Someone said try tagging @lars so here goes nothing
Clean install of latest NVIDIA driver (choose Custom install and enable the Clean Install checkbox).
Delete the content of %APPDATA%\McNeel\Rhinoceros\8.0\Plug-ins\RhinoCycles (9bc28e9e-7a6c-4b8f-a0c6-3d05e02d1b97)\data and %APPDATA%\NVIDIA\ComputeCache
I am getting this same issue with not being able to ‘see’ the CUDA or Optix tabs using the latest version of NVIDIA (studio) driver on a Dell Inspiron 16 plus 7640. I have eveI disabled the Intel GPU, restarted Rhino and ran SystemInfo and the output doesn’t even identify a CUDA capable device. Were you able to fix your issue?
