If you use VmaAllocationCreateInfo::usage, it is just internally converted to a set of required and preferred flags.

Custom memory pools

If you allocate from custom memory pool, all the ways of specifying memory requirements described above are not applicable and the aforementioned members of VmaAllocationCreateInfo structure are ignored. Memory type is selected explicitly when creating the pool and then used to make all the allocations from that pool. For further details, see Custom memory pools.
