Game lagging on a a huge map after you got all of the World Map???Heres a little help

[Olli1980]

If your game gets very slow after you finished your turn (it hang on me sometimes 2-3 minutes) once you "discovered" all of the World Map,try to zoom into the map all the way and then hit the "end turn button"...helped me a lot

Try turn off the Animations on graphic options, it help me alot. Click on "animation frozen" and see if that will help?
