Linux / GTX 675MX

Hello,

If i’m not wrong, vulkan is ok with my graphic card (in fact i can run vulkaninfos on Window).
So i have the last nvidia driver :

I just download and install this : https://github.com/KhronosGroup/Vulkan-LoaderAndValidationLayers

But when i try to run vulkaninfos:

There is something wrong with my config? Kenerl too old? (4.1.15-r1/gentoo-sources)
Maybe Bumblebee incompatible? (The default config is ok)

Any help will be nice
Thansk

Ps: I can run my nvidia with optirun whitout any problem

I have tried tu run vulkan without bumblebee, when you force nvidia card like this https://wiki.gentoo.org/wiki/NVIDIA/Optimus

But i have exactly the same outpout.
My graphic card is not supported yet? I need to do something?

Thanks
