### Remarks

Start execution of the enqueued operations on the device. On some platforms the underlying implementation or driver flushes automatically, on others it is up to the user to call [ReferenceContext.Flush](/engine/6000.6/script-reference/unityengine/lighttransport/referencecontext/flush.md). The [ReferenceContext.Flush](/engine/6000.6/script-reference/unityengine/lighttransport/referencecontext/flush.md) method returns immediately.
