As I understand it, with a default 1 buffer, much of the DSP work is happening independently of how the DAW reports CPU usage (which is usually calculated by how quickly the current audio buffer is processed, I believe).It does. The lower the set buffer size, the more CPU will be utilized.
I don't know what technical background it has that a setting of 0 is also the only setting which will report the real CPU usage to the DAW, but, I'm sure I wouldn't understand it either, if they explained it.
At 0, everything is done in the audio loop, so it takes longer to process for the DAW which consequently reports a higher, more accurate load to the DAW.
In both cases, the actual work the CPU does to calculate the synth is basically the same*, it's just that in the first case, the DAW can't report on what it doesn't know is happening.
* Though there may be performance optimisations going on, resulting in some efficiency gains.
