Vulkan SDK: No physical device found (Ubuntu 14.04 with NVIDIA 367.35 driver on GTX 460 + 1070)

Hello,

Sorry for posting about Vulkan SDK in the CUDA section but I haven’t seen any Vulkan section in the “Accelerated Computing” part of the forum.
That’s why I posted my issue in “Visual and Game Development” but no answer for a week :(

Here it is :

If someone knows the Vulkan SDK enough to help me, please follow the above link ;)

Thanks in advance,
Bruno
