Metal Resource Residency With Bindless

[JonahGoldsmith]

When using bindless model how does MoltenVK track resources that need to be resident? If i just have a huge array of UAV resources and im only calling BindDescriptorSet once what goes on behind the scenes? Is every draw call hit with a useResource call for every single resource created as a UAV? Or is there behind the scenes tracking somehow

Yes. Currently MoltenVK must make useResource calls for each resource in bound descriptor sets.

We're looking for ways to optimize that, but it is what it is for Metal.
