+## 命令队列
+DX12的命令队列被抽象为ID3D12CommandQueue。使用ID3D12Device::CreateCommandQueue()来创建。
+```c++
+Microsoft::WRL::ComPtr<ID3D12Debug> mCommandQueue;
+D3D12_COMMAND_QUEUE_DESC queueDesc={};
+queueDesc.Type = D3D12_COMMAND_LIST_TYPE_DIRECT;
+queueDesc.Flags = D3D12_COMMAND_QUEUE_FLAG_NONE;
+ThrowIfFailed(md3Device->CreateCommandQueue(&queueDesc,IID_PPV_ARGS(&mCommandQueue)));
+```
