I highly suggest you to try the "Client ruler script optimization" from the 1.1 fixes (see bovi's sig).

There are some very rare issues reported of ghost generals or clones being spawned, but many (me included) run the script for a long time without any problems occuring, and I played about 10-15 campaigns, most of them at least about 100 years (->400+ turns).

The loading speed between the turns is reduced by factor 2 minimum, without the script I easily could read some pages of a cartoon or finish a page in the newspaper or the like, now there's non-stop action And I never would want to miss my "Amicvs Popvli Romani" sitting in the Sahara or in the thickest forests of Germania
