D3D12_COMMAND_QUEUE_PRIORITY

Defines priority levels for a command queue.

Syntax

typedef enum D3D12_COMMAND_QUEUE_PRIORITY
{
    D3D12_COMMAND_QUEUE_PRIORITY_NORMAL = 0,
    D3D12_COMMAND_QUEUE_PRIORITY_HIGH = 100,
    D3D12_COMMAND_QUEUE_PRIORITY_GLOBAL_REALTIME = 10000
} D3D12_COMMAND_QUEUE_PRIORITY

Constants

Constant	Description
D3D12_COMMAND_QUEUE_PRIORITY_NORMAL	Normal priority.
D3D12_COMMAND_QUEUE_PRIORITY_HIGH	High priority.
D3D12_COMMAND_QUEUE_PRIORITY_GLOBAL_REALTIME	Global realtime priority.

Remarks

This enumeration is used by the Priority member of the D3D12_COMMAND_QUEUE_DESC structure. An application must be sufficiently privileged in order to create a command queue that has global realtime priority. If the application is not sufficiently privileged or if neither the adapter or driver can provide the necessary preemption, then requests to create a global realtime priority queue fail; such a failure could be due to a lack of hardware support or due to conflicts with other command queue parameters. Requests to create a global realtime command queue won’t silently downgrade the priority when it can’t be supported; the request succeeds or fails as-is to indicate to the application whether or not the command queue is guaranteed to execute before any other queue.
