Hi, Gabriele makes me notice that you are working with v1.55. Better to perform a clean installation of an older version of Nvidia drivers. Try with 397.93, but probably you need an older version: https://www.nvidia.com/download/driverR ... 4624/en-us ciao Beppe
I also have the "no cuda gpu's" error. My Octane version: 4.05 standalone GPU: GTX Titan 1. I uninstalled all drivers via DDU. 2. I opened the software without installing any driver. It worked. 3. I installed Nvidia Driver 442.19. Same problem happened again. 4. I tried several other driver versions the same problem happened in all the instances. 5. I installed 3.08 the problem is still there.
It looks like installing a driver is preventing octane to see the graphics card.
Hi, v3.08 is too old, please use v4.05, and try to perform a clean installation of 419.67 Nvidia Creator Ready driver: https://www.nvidia.com/download/driverR ... 5178/en-us To perform a clean installation, please follow these steps:
Then download and run GPU-Z: https://www.techpowerup.com/gpuz/ And share a screenshot from the Graphics Card tab, for all the available Nvidia GPUs, thanks:
Hello Beppe, Thank you for the instructions, 1. I installed windows 8 version of 419.67 since my OS is W8.1 2. I performed a clean installation 3. I still see the same error in Octane 4.05
This is my GPU-Z screenshot. I see that CUDA is not marked after 419.67. ( please note that just after the DDU, I was able to see CUDA ).
Is CUDA still unchecked in the GPU-Z panel? You need to find an Nvidia driver greater than 419.67 that works for you. Unfortunately I don’t have other reports from Win 8.1 users, normally it is Win 7 or Win 10. ciao Beppe
