I started a new game after updating to 1.19f, and everything went fine until the game tried to show the map. The fog of war displayed fine, but then the map just has a bunch of redrawing polygons on it.
Other games work fine, haven't updated hardware nor drivers since playing previous version (which worked fine).
Using ATI Radeon 5670 video card on Windows 7 x64.
Any help would be greatly appreciated.
