## 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)));
```
