Cubase Midi latency

Hi,

I’m using cubase on xp with a very fast latency.
However starting 16/32 quantize mode, i do have notes whose are delayed.
I’ve seen a midi compensation parameter in the external instrument section, but i don’t really understand/didn’t manage to have something more precise?
These os also one in the preferences settings ?

Thanks in advance,
Have a good day,
Rgds,
