Single VkBufferView, single VkBuffer on single allocation

Hi all,

The following blog - vulkan memory management - proposes to use a single VkBuffer for a memory allocation (or a couple of them) and then sub-allocate from this buffer using sub-ranges.

Does this performance optimization also apply for VkBufferViews or is this a lighter object that we can use for each of the sub-ranges?

Thanks,
George
