I am trying to play AOE III but it is getting really anoying. In single player on my Desktop PC I have no issues at all but on my Notebook I get it here and there. The main issue though, when I play on the two PC's over my LAN (not online). I get what I like to call "Stutter Jitter Minor LAG Syndrome (SJ-MLS)", it is just enough to make you mad (real anoying) but not enough to make you quit. What can I do??

I have the latest game update, all of the latest drivers, bios, updates and firmware. Also, I just defraged both PC's yesterday.
