I first loaded up the game, patched to 1.06 in Steam this morning, and found that for some reason, the map is covered by horizontal rows of triangles and rectangles. They persist across map modes, from the main menu into the game itself, and, when I zoom down as closes as I can, they follow the contours of the landscape (rising and falling over hills). I've reinstalled, had steam check the fragmentation and presence of the game files, activated and deactivated all my DLC (SoI, African Units, Mongol Faces, Extra Crests) and nothing seems to change. Any idea what could be causing this. I'm playing on a relatively ancient graphics card (ATI 4300 or so) on a decent computer, and have never had an issue like this before. Help?
