Nano Mode Question

Hi All,
Out of curiosity do I have to run H4PC in Nano Mode? As far as I can tell it doesn't say I have to in the manual. I run a server with static IPs on a laptop and log in with my PC console in server mode like I did with H3.
A couple of weeks ago I started having issues updating cues until I switched my console to a client. Both are run in Full Mode.
Thanks in advance
