Loving the game on the Insane map scale. [It's about time someone made a galaxy map feel like it was actually galaxy-sized!] HOWEVER, after 10 minutes or so, the game drags really, really bad. That goes on for about 5-10 minutes and then it goes back to normal. Then 5-10 minutes later, it's dragging again. Over and over again. It's not like my system is ancient or anything. I can't imagine how 8 Gb of RAM is inadequate, or that 4 CPUs can't keep up the pace. The only thing I can imagine causing this cyclical dragging is that the game is poorly cycling RAM cache data.
Please tell me if I missed something on the Option settings. I have the most recent GeForce driver for the video card -- 352.86 -- and all of my various drivers are up to date for that matter. I deliberately set my Graphics settings to Low, but that had no effect. Below is most of the info from a dxdiag file. (I didn't see any file attachment option, so sorry for the wall of text.)
