MTLCounterSampleBuffer

Declaration

protocol MTLCounterSampleBuffer : NSObjectProtocol

Mentioned in

• Converting a GPU’s counter data into a readable format
• Confirming which counters and counter sets a GPU supports
• Converting GPU timestamps into CPU time
• Creating a counter sample buffer to store a GPU’s counter data during a pass
• Sampling GPU data into counter sample buffers

Overview

Create a counter sample buffer by calling an MTLDevice instance’s makeCounterSampleBuffer(descriptor:) method. See Creating a counter sample buffer to store a GPU’s counter data during a pass.

You can store a GPU device’s counter set data only with an MTLCounterSampleBuffer instance that you create from the same device. See Sampling GPU data into counter sample buffers for information about storing counter sample data in a counter sample buffer.
