Here are the problems : All the land is white, can't see the differences between grassland, plains, etc. No I didn't select arctic terrain! Secondly, there's a problem with the water. Each water tile is divided in two triangles, one black triangle and one blue water triangle. Strange??? I know I don't have the minimum system requirements concerning the video card, maybe it's because of that, but anyway I post it. I uploaded my DxDiag file.
