# MTLCounterDontSample

A sentinel value that instructs an encoder to skip sampling a counter as the GPU runs the encoder’s pass.

## Declaration

```swift
var MTLCounterDontSample: Int { get }
```

## Mentioned in

Sampling GPU data into counter sample buffers

## Discussion

Discussion You can skip sampling at specific stages by assigning this sentinel value to the following properties instead of an offset to a counter sample buffer:  |   |   |   |   |   |
