An update. I am on turn 450 on a huge continent map with 3 AI on king level and there has been no freezing, nor has the game rebooted the computer via BSOD. Occasionally when bringing the laptop out of sleep mode, I get lag and a lot of grey tiles, but after a while they go away. Scrolling from city to city in city view does not lock the game up either. I was in a war with Catherine (Russia) from 1818 to about 1960. She then offered all her money 3500+ and nothing in return, for 10 turns of peace. She never attacked again. Since she left her lands neglected the whole war, her land is now "carpeted" with workers doing catch up. At the beginning of the war, she was 200+ points ahead of me. Now she is 100 points behind. She will probably sell them all to build her space ship. Unless I get Utopia built first.
