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 > In…

Any news? A little bit stressed about this

[image] Japhy: It looks like 1.32+ is needed Your system info is still showing 1.31.. Which i believe is the current RC [image]

[image] Japhy: showing 1.31 8.31! @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 GPU Kernels Compile Log: COMPILER OUTPUT: Compile started, waiting for results… Start compile process with device count: 1 (Optix) Compile failed Compile sta…

Out of curiosity, does the latest version of Blender permit you to do OneAPI rendering (Intel)?

Thanks for the update. I’ve assigned this to Lars to take a look at.

[image] nilceros: i can se the drivers and choose which one I want. But still in the Retraced window it says cycles@CPUx32 Apologies if you think this is a dumb question, but just in case… You are ticking the option you want and not just choosing the tab? [image]

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.
