The C64 had no jitter but it wasn't able to record real human touch.
I've got an Atari ST with the latest Atari Cubase version, it's also
without jitter and for most cases it has enough ticks.

Btw. I did run the EMC2 / HAL latency test and max jitter was < 8000 ns,
so this latency test might show that some parts of my computer are ok.
Kernel for the EMC2 live cd is a rtai patched one.
