You aren't running a tonne of process's while playing are you?, by the looks of things the only problem could be a lack of RAM cache due to a nearly filled hard drive and tonnes of processes's. I've managed to do 7 v 2 land battles with over 150 units per side with cannons on max graphics and it's run fine, and i pretty much have similar specs as you.RabbleKnight said:What the ****, sea battle and huge boarding action is fine but things get choppy on a 3 vs 6 land battle.
Spec:8 gig of ram
