I may be wrong but Windows mixes various sources into single streams, so if a software outputs 16/24 bits 48000Hz and you have 24bits 48000 Hz set, Windows just copies the data over without processing and no cpu usage. Only music ripped from audio CD's (mp3) is in 44100 Hz and can be easily resampled to 44100 Hz.Ĭonversion from 16 bits to 24 bits is also super easy and uses barely any processing power (almost unnoticeable, and worth it).
I usually set it to 24 bits, 48000 Hz because that's the most common format everywhere.
