Sector Siege needs improvement

I was talking about making it an option to disable the fog but if the ai can't see you even with fog off then your right unfair player advantage and any performance benefit is lost to downgraded game play.

I like the independent targeting nature of the turrets and wouldn't want to compromise that. Its a hallmark of both this game and harbinger. Does the game hold the date in memory from each call for a while? Could this be what eating up processing power?
