The strange thing is that Rhino itself clearly sees and uses the NVIDIA GPU for OpenGL/viewport display, and Windows/NVIDIA also detect the GPU correctly. The issue seems to be specific to RhinoCycles / Raytraced render device detection.
RhinoCycles_ListDevices
We have 1 device
Device 0: CPU > Intel Core Ultra 9 275HX > 0 | False | Cpu | GPU: False
The Raytraced viewport text in the bottom corner also shows:

I also checked with nvidia-smi in windows command prompt. But it the graphic card is listed there.
Have tested the followning:

@nilceros, As Japhy said, you need the latest SRC candidate to take you up to 8.32 or higher. That should allow Rhino to use your 5070 Ti - it has done for my 5070.
Thanks! After the update to SR32 i can se the drivers and choose which one I want. But still in the Retraced window it says cycles@CPUx32

Latest: It works. I left the Rhino on Retrayced for awhile after recompiling the kernels. And it started to work. It took some time for the render to use the GPU as well. Don’t know why.
Thank you all for all the help.
