GPU not recognized

Hi, I've used DaVinci Resolve 15 for a while now and although my hardware is low-end I'm still happy as Resolve is still way better than any other video editing software on Linux.

I've tried Resolve 16beta4 now and my GPU is suddenly not recognized after a fresh install.
This didn't happen with version 15 ever, so could it be that the hardware requirements changed?

I have a GeForce 840M and I use bumblebee (primusrun).

Here some screenshots:

Resolve 15


Resolve 16beta4



Specs:
Installed via makeresolvedeb
OS: Debian GNU/Linux 9.9 (stretch)
Kernel: 4.9.0-8-amd64
GPU: NVIDIA Corporation GM108M [GeForce 840M]
RAM: 8G

PS: I'm using the free version of Resolve

OpenCL is for AMD, that's why (actually, if I remember correctly, it's "open source") but you should have other options in that drop down list.

Yes right, I posted the wrong option, I've updated the screenshots in OP with CUDA selected.
Which btw. look exactly the same.

Same issue with beta5, GPU is not showing up.

I very surprised that old and very low power GPU works. It’s might be a driver issue but is you can’t find a driver that works consider a GPU less than 2 years old.
