Neither Rhino 8 nor the R9 WIP show the GPU tabs on the Render Options page. Notwithstanding the 5070 laptop GPU arrived after Rhino 7, the latter does list it, so it is difficult to see why the later releases have a problem with it. [image] [image] SystemInfo: Rhino 8 SR31 2026-4-14 (Rhino 8,…

Deleting those folders hasn’t helped.

[image] Jeremy: Setting the laptop to use Nvidia exclusively for everything doesn’t help. Did you use the Lenova Vantage app to change the setting?

No, the Nvidia Control Panel. I don’t think that setting is available in my edition of Vantage. Also, let’s not lose sight of R7 working OK…

Is there by chance a file called “disable_gpus” in this location “%APPDATA%\McNeel\Rhinoceros\8.0\Plug-ins\RhinoCycles (9bc28e9e-7a6c-4b8f-a0c6-3d05e02d1b97)\settings”? If there is close all running Rhinos and delete that file.

Hi @lars That file is present and is zero bytes. I deleted it but when Rhino 8 subsequently started it recreated the file. The R8 started after deleting the file still does not show the GPU tabs. Regards Jeremy

I also find it curious, given it is apparently fixed now, that Rhino also doesn’t see your Intel Arc 140T as a valid render device. As OneAPI has been shown by at least one user to be fixed on his 140V for both Rhino 8 (and WIP I assume), then I would expect the Arc to show as well.

@lars , @Japhy FWIW, as RhinoCycles in R7 utilises the RTX 5070 Laptop GPU OK, I thought to check Cycles in Blender 5.1 - that also shows the Nvidia GPU option for CUDA and OptiX.

Thanks for testing. Rhino cycles initialization fails when running through the available GPUs on the system. Unfortunately if one GPU causes issues it will disable them all at the moment. I am working on a custom Rhino 8 build that I will hopefully be able to send to you tomorrow for testing.

Hi Jeremy. You may want to try to set Rhino to use Arc 140T as the primary GPU for the viewport and see if it solves the issue on the missing RTX under Cycles. You could go clicking WIndows START button and type GRAPHICS SETTINGS, and find RHINO 8 in the App List. If not, you could add EXE file. S…

@jeremy5 The fix should be in Rhino 8 SR32 which is available. This does not include a solution for the Intel GPUs. I still have to look into that.

@Aleksey_Gavrilov Could you send me a Rhino System Report, please.
