If you haven't already done so, read this section of the installation guide:

Assuming you are using Windows, if you are using the built-in sound card
you will be using an "MME" driver which has very high latency.  It is possible
for Mobius to compensate for this so that your overdubs will line up but
you have to enter the right values into the latency fields in the
Audio Devices window.  Sometimes the driver is able to tell us what
the latency is, other times it can't and we have to enter it manually.
This is explained in the manual.

If you use a pro audio interface it will come with ASIO drivers that
have very low latency.  Often people don't even bother tuning latency
compensation since it is so slight that it is hard to hear even if it
is off by a few milliseconds.

As an alternative to buying a pro interface you could also try
ASIO4ALL which will give the built-in sound card an ASIO driver.  I have
had success with this, but if you're serious about sound quality you
should still consider an external interface.

I'm not sure what this was referring to, but you can certainly tune
latency compesnation for exact alignment of overdubs and once set it
won't drift unless you are also changing your physical location
relative to your monitor speakers.
