I am talking about PD's CPU meter. I don't have the impression that PD

anything over 100 in PD's meter will lead to glitched audio. I am just
wondering if it will be much more when I load other videos and transition
between them.
Pd will only use one core, and one core for the GUI. There are ways to
distribute the load over several cores, e.g. [pd~] or use several
instances of Pd that communicate with each others:
Pd will use multiple threads for a few specific tasks, like streaming
soundfiles from disk (with [readsf~]).
Gem will also try to utilize multiple threads for special tasks as well,
like image acquisition.
e.g on backends that support it[*], you get two tasks, Pd's main task
(with all audio and video rendering) and one decoding task (per image
acquisition object).

thread - but then it does multithreading on it's own.
