ovr_CreateTextureSwapChainVk returns with ovrError_Unsupported (-1009)

On my Linux machine nvidia drivers are going at 381.09 and they have the mentioned instance extension with GTX 960. I'll try the 381.89 next.
Update: The 381.89 has the VK_NV_external_memory_capabilities. I think it's got to do something with the 780 ti being a Kepler and 980 GTX being a Maxwell.
Update #2: yet... https://devtalk.nvidia.com/default/topic/994252/?comment=5086174 he's got the thing in the list. Maybe I just have to go with even older driver?
Update #3: no. I just tried the oldest driver I can get from the archive, which should be from May. Still I don't see the KHX version of that instance extension.
Finally decided to ask it there as well.. Maybe they know what's going on: https://devtalk.nvidia.com/default/topic/1021776/vulkan/vk_khx_external_memory_capabilities-missing-on-gtx-780-ti/
