In the last video we started implementing an allocator class for managing descriptor heaps. After writing the initialize and allocate functions, we ran into a problem caused by the fact that resources and descriptors can't be removed in an immediate fashion, because we're using a multi-frame render scheme and those resources could still be in use by the GPU. So today, I'll start by setting up a system for deferring release of resources to a point that we're sure they're no longer referred to by the GPU. After having done that, we can continue writing the rest of the heap allocator class. (Red Episode)
