Campaign map slowdown

[nodachi7]

Hi peoples, i have just picked up Medieval 2 kingdoms on sale (prolly cause of ETW). I played Medieval 1 forever and loved it.

My problem is when i scroll around the campaign map it hits a massive slowdown over the french region and any actions in this area take an incredibly long time. My mouse cursor is slow and troops move really slow.

When i scroll to the edge of the map its fast again.

I though it was maybe a patch issue so i D/L 1.2 but the game says its running 1.3.

Its not my PC:
Q9450
ATi 4870
500GB hd
4gb Ram
Vista 32bit
this plays all other newer games just fine.

I dont have any slowdown in battles/sieges etc, just campaign map only.

Any help would be greatly appreciated as the game is frustrating me now.

I used to have that problem too back in the day, but it was my PC

I had a similar experience. Vista can easily use a USB Flash Drive as extra virtual RAM, so I got an 8 GB drive for a few US dollars. When you plug it in, just set it to be extra RAM (I think it is called readyboost) and boom. Everything in the game works faster.
