Re: [PATCH v4 0/1] MR523: vkd3d: Use mutable descriptors if available.

[Giovanni Mascellani (＠giomasce)]

Another thing that `VK_EXT_mutable_descriptor_type` enables is flags `VK_DESCRIPTOR_POOL_CREATE_HOST_ONLY_BIT_EXT` and `VK_DESCRIPTOR_SET_LAYOUT_CREATE_HOST_ONLY_POOL_BIT_EXT`. How hard/useful would it be to support those? AFAIU using those bits we're less constrained by the total number of descriptors in unused heaps and by synchronization requirements.
