I have been enjoying my games recently because I have started roleplaying the different civs how I think would be played, but after I get to turn 400 or so(normal speed) the slowdown has been unbearable, such that I have been reading novels in between turns, which last about 5-6 minutes apiece. I play standard size maps with 3 continents, and by this time in the game there are usually 6-8 civs left in play. To make matter worse, if anything weird happens, like a Tree ent defender or I complete the Rites of Oghma or Genesis, the game just freezes completely. I'm playing on high graphic settings, does that change anything? I'm running a 2 Gig processor with 3.25 Gigs of RAM and a Nvidia Geforce 9600 GT video card. any suggestions on ways to speed up the game turns?
