## 常數

| 常數 | 描述 |
| - | - |
| D3D12\_COMMAND\_QUEUE\_NONE | 預設命令佇列。 |
| D3D12\_COMMAND\_QUEUE\_DISABLE\_GPU\_TIMEOUT | 表示要為此命令佇列停用 GPU 逾時。此值在 XBOX 上會被忽略。 |
| D3D12XBOX\_COMMAND\_QUEUE\_FLAG\_PRIORITY\_MASK | 用於擷取優先順序位元的位元 AND 遮罩。 |
| D3D12XBOX\_COMMAND\_QUEUE\_FLAG\_PRIORITY\_SHIFT | 用於在 D3D12XBOX\_COMMAND\_QUEUE\_PRIORITY 值與 D3D12\_COMMAND\_QUEUE\_FLAGS 優先順序值之間轉換的位移值。 |
| D3D12XBOX\_COMMAND\_QUEUE\_FLAG\_PRIORITY\_LOWEST | 最低的相對優先順序。 |
| D3D12XBOX\_COMMAND\_QUEUE\_FLAG\_PRIORITY\_LOWER | |
| D3D12XBOX\_COMMAND\_QUEUE\_FLAG\_PRIORITY\_LOW | |
| D3D12XBOX\_COMMAND\_QUEUE\_FLAG\_PRIORITY\_MEDIUM | 預設優先順序 |
| D3D12XBOX\_COMMAND\_QUEUE\_FLAG\_PRIORITY\_HIGH | |
| D3D12XBOX\_COMMAND\_QUEUE\_FLAG\_PRIORITY\_HIGHER | |
| D3D12XBOX\_COMMAND\_QUEUE\_FLAG\_PRIORITY\_HIGHEST | 最高的相對優先順序。 |
| D3D12XBOX\_COMMAND\_QUEUE\_FLAG\_PRIORITY\_DEFAULT | D3D12XBOX\_COMMAND\_QUEUE\_FLAG\_PRIORITY\_MEDIUM 的別名。 |

## 備註

此列舉由 <a href="https://msdn.microsoft.com/library/windows/desktop/dn903796(v=vs.85).aspx">D3D12\_COMMAND\_QUEUE\_DESC</a> 和 [D3D12XBOX\_COMMAND\_QUEUE\_DESC](/zh-TW/reference/graphics/d3d12_x/structs/d3d12xbox_command_queue_desc) 結構使用。

此列舉相當於 D3D12/PC 列舉 <a href="https://msdn.microsoft.com/library/windows/desktop/dn986722(v=vs.85).aspx">D3D12\_COMMAND\_QUEUE\_FLAGS</a>。
