# maxCommandBufferCount

Sets the largest number of outstanding input/output command buffers a queue can have at any point in time.

## Declaration

```swift
var maxCommandBufferCount: Int { get set }
```

## Discussion

Discussion The input/output command buffers that count against this limit are those that are currently executing in a queue or waiting to execute. The command buffers that have finished executing no longer count against this limit.
