Manages a pool of WebGPU timestamp queries for performance measurement. Extends the base TimestampQueryPool to provide WebGPU-specific implementation.

Reference Tables

Constructor

Signature

Methods

Method	Description
.allocateQueriesForContext( uid : string ) : number	Allocates a pair of queries for a given render context.
.dispose() : Promise (async)	Dispose of the query pool.
