It is indeed not implemented, but since the effect is completely transparent to the application, it doesn't need to be implemented for correctness. I cannot do anything about poor performance.
setting dxvk_log_level to none fixes the performance issue.

Having thought about this for a bit, it does not make sense for DXVK to implement these functions. In theory, they request the driver to allocate new memory for a backing resource, which can in some cases improve things, but I don't see how DXVK could benefit from this. In situations where doing so is truly beneficial, it already does so anyway.
