GPU usage is under 10% in render mode

Hello everyone,
I downloaded the demo version Octane v4.0 for Cinema 4D and the v3_sample_scenes .
I opened the "light-paint.c4d" project and I want to do a render test. I started the render process, but my GPU usage is under 10% and take almost 5 minutes for one single frame...
I have not changed any settings, (in Rendered option is selected Octane renderer), I use Nvidia GTX 980, i7 7740x, 32GB Ram cl13

What I noticed is that I have the same problem in the older version > octane 3.07, also with any scene, even if I open a sample scene or do something made by me...

How can I fix that?

Regards!

Hi,
are you using GPU-Z for monitoring your GPUs while rendering?

About the specific scene, the Kernel settings are not optimized.
For example in v4, you can reduce the Max Sampling at 1024, and enable AI Light, the rendering should be much faster:

Thank you for your reply bepeg4d

Yes, I use several GPU monitoring software, also in the Task Manager > Performance, the GPU is 0 -10% (cinema 4d GPU 0%) ...
I have windows 10 pro, GPU Asus strix 980 OC with all drivers updated.
How can I fix this?

Thanks!
