# MTLCounterSampleBufferDescriptor

A group of properties that configures the counter sample buffers you create with it.

## Declaration

```swift
class MTLCounterSampleBufferDescriptor
```

## Mentioned in

Creating a counter sample buffer to store a GPU’s counter data during a pass

## Overview

Overview To create a new counter sample buffer, create and configure an MTLCounterSampleBufferDescriptor instance, and then call an MTLDevice instance’s makeCounterSampleBuffer(descriptor:) method. See Creating a counter sample buffer to store a GPU’s counter data during a pass. Each new sample counter buffer inherits the values of the descriptor’s properties when you create it. You can modify a descriptor and reuse it to create other counter sample buffers, which has no effect on existing counter sample buffers.
