> latency you mean?

Maybe timing is the wrong word. Latency is definitely a related concern.

If something needs to fire every 1209 ms then it can't get fired in 1232 ms this time and then 1198 ms next time. Maybe a better term would be clock jitter or drift?

As I understand it, a DAW needs something close to a RTOS.

Linux can run specific apps with realtime priority since 6.12. Just gotta configure your audio stack to run that way.

Ah yes, I understand - yes as the other comment says, kernel supports it but most distros aren't configured that way out of the box, but it's pretty simple in most of them - on Arch you install the `realtime-privileges` package and add your user to the `realtime` group, the audio server and DAW software takes it from there.
