After a 6-9 month hiatus I finally broke down and purchased Conquests. I played 2-3 games in the traditional mode to get the feel of the new game and looked forward to giving RAR a try once I was up to speed. Downloaded and am playing my first game now using the large Earth map from Kal-el with resouces (no barbs - I tried with barbs first playing as the Celts and got creamed within 10 turns, so started a no barbs game instead).
The game ran great and I had not encountered any noticable problems until now. I'm in the late Medieval ages and most of my workers have been upgraded to Laborers. I don't know if that is the reason, but as soon as I upgraded most of my workers, the game has turned into a crawl graphically. The time between turns is the same as always (long, since I'm using all the civs on the huge map). But scrolling around my map now has all of the sudden become extremely slow. I can't think of anything else that has changed or added to my game recently to cause this sudden graphical slowdown.

I am among 2 other nations in the tech lead and have just overtaken the Aztecs for the histograph lead.

I didn't have time to read all 30+ pages of this post. Anyone else experiencing this problem?
If anyone wants a save I've got it. Let me know.
Does the DYP site still have a 'testers' bulletin board? Been so long since I was there I couldn't find it.
