User level: Level 1 (4 points)I've been having a latency issue with Logic Pro, even when the I/O Buffer Size is set to 32 or 64. I feel like this shouldn't be happening because I just got a brand new MacBook with crazy specs. When this happens, I'll start to turn off plugins but that doesn't help.
What can I do to stop noticable latency with "bigger" sessions???
MacBook Pro, Apple M5 Pro chip, 64 GB memory, Tahoe 26.4
Logic Pro 12.2

When "delay compensation" is enabled, which is the default setting to avoid phasing issues, every latency caused by a plugin is accumulated (!) to the total latency. Some plugins are producing more latency than others, like most pitch-related plugins, analog-simulations, de-noising/repair stuff, any plugin that is using fft or other time window, also some software instruments .... You could try to freeze the tracks if possible.
... and also check sound card related latency. If the Roundtrip in ms is higher than lets say 20 or 30 ms at a small buffe rsize, you should restart your computer and see if it has changed. What sound card are you using?
