GPU's not showing in settings

I just updated my nvidia drives to the current version and updated Octane to the most current stable version. (3.08.2-R2.1)
I now am unable to see any GPUs available in the settings table of C4D octane or Octane standalone.
The GPU's are recognized in the Nvida Control Panel. There are quad 780 6gb.

anyone else experiencing this? I guess all I can do is go back to an earlier driver but I was having issues with my driver crashing so it would be great to have a more updated driver but I guess I will have to take what I can get.

Thanks for any advice.

Hi,
probably, the CUDA part of the drivers has not been installed correctly.
Please, use DDU for completely removing the nvidia drivers:

And perform a clean installation of 391.35 nvidia drivers.
There is a known issue between Win 10, 39x.xx Nvidia drivers, and motherboards with PLX chip in 4x GPUs mode, have a look here:

Thank you for the reply, unfortunately the settings devices is still blank after using DDU and installing 391.35.
I am also on Windows 8.1.

Any other thoughts?

Thanks!

Hi,
could you see the GPUs in Device manager, and in the Nvidia control panel?
What happen if you open Standalone?

Yes I can see them in my system and are recognized by Nvidia control panel.
I see nothing in both the stand alone and C4D Plugin for available GPU's.

Hi,
please, open Standalone 3.08.2, than go to File/Preferences/Devices, and share a screenshot, thanks.
Try to use GPU-Z to check if CUDA is enabled on the cards:
