That moment when audio starts (new stream / scene load) and your main thread stalls? Classic hitch.

Unity 6.3 calls out an Enhanced Audio change that moves expensive platform audio operations off the main thread—aimed specifically at reducing main-thread hitches.

Quick win: reproduce your worst “audio-start hitch” in a Development Build and re-capture the same moment after upgrading.

Business translation: fewer hitches = better first-session retention and fewer “laggy” reviews.
