I was wondering if anyone could offer my any help with playing huge maps well. I made a custom map and was trying to play it against 9 unfair AI with maxed settings. 6 stars, 300ish planets. Everything was fine for about an hour but then it slowed to a crawl. I have a AMD 965 3.9 ghz, vista 64, 8gb crucial 1600 ddr3, Evga 260-216 625 cc 1295 shader clock, could this be a hardware bottleneck? What systems do you guys play these huge maps on?
