what(): failed to find any capable Vulkan physical device

[bcizmeci]

When I compile and try to run the test. the GPU is not detected (RTX 3070, cuda 11.4, vulkan version: 1.2.131.2-1)

Please make sure you download the correct version of a BETA driver from https://developer.nvidia.com/vulkan-driver.

I'm reproducing the same issue with the vulkan beta driver (on Fedora 36 with GM107GL).

modinfo -F version nvidia 515.49.15

Here is the vulkaninfo ouput https://paste.centos.org/view/3e342545

Is the hardware is missing any required feature to function ? (for at least, to decode h264 ?)

Thanks.

Okay worth retesting later according to https://github.com/nvpro-samples/vk_video_samples/issues/18#issuecomment-1248192770
