# makeCommandQueue(maxCommandBufferCount:)

Creates a queue you use to submit rendering and computation commands to a GPU that has a fixed number of uncompleted command buffers.

```
func makeCommandQueue(maxCommandBufferCount: Int) -> (any MTLCommandQueue)?
```

## Parameters

`maxCommandBufferCount`

An integer that sets the maximum number of uncompleted command buffers the queue can allow.

## Return Value

A new [`MTLCommandQueue`](/documentation/Metal/MTLCommandQueue) instance if the method completed successfully; otherwise `nil`.

A Command queue can only submit commands to the GPU device instance that created it.
