DVDFab 12 Bits H265 GPU problem.

I have a problem when try to convert a video to H265 at 12 Bits, it's supposed to use the GPU but it doesn't use it.

When i do the same convertion but at 10 Bits the GPU is used like should be.

Video showing the problem: https://www.youtube.com/watch?v=8XMPmOtngwE

Someone who use DVDFab have the same problem?

GPU: 10810 TI
Nvidia Drivers: 436.48
DVFab version: 11.0.5.1

It has to do with hardware capability. 12 bit HW encoding is not supported at the moment. See https://developer.nvidia.com/nvidia-video-codec-sdk. I have no idea if/when 12 bit HW encoding will be added in the future.

If you read a bit further after your last red marker, you'll see that it used x265 to encode that video - ie. a software encoder. Not your GPU.
