```

## Return Value

## Discussion

Discussion A command queue can only submit commands to the GPU device instance that created it. important: The command queues you create with this method allow up to 64 uncompleted command buffers at time. This method is the equivalent of passing 64 to the makeCommandQueue(maxCommandBufferCount:) method.
