If you mean device drivers, it can be a bit hit or miss, generally stuff works but for example I have an SSL audio interface and while the audio works, it's missing a lot of the configuration options that the Windows drivers give you around customisable audio routing.
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.
You might need to tweak kernel settings for better latency https://wiki.archlinux.org/title/Professional_audio#Optimizi...
