# MTL4TimestampGranularity

Provides a hint to the system about the desired accuracy when writing GPU counter timestamps.

## Declaration

```swift
enum MTL4TimestampGranularity
```

## Overview

Overview Pass these values to writeTimestamp(granularity:counterHeap:index:) and writeTimestamp(granularity:after:counterHeap:index:) to control the desired accurracy of the counter sampling operation.
