## AI Description
This C++ component provides synchronization primitives for managing GPU operations in a DirectX 12 environment. It includes functions to wait until the GPU is idle, wait for multiple fences, query fence values, and release fences. The implementation uses a pool of available fences to efficiently manage resources and ensure that commands are executed on the correct GPU.
