Hello, I have a graphic bug when i play at this game. If i'm in the 4 city, i have not problem but when i'm in the campagn, le ground is transparant. I modified all option in Regedit (Direct3D), change the Windows Version, installed d3dx9 with winetricks or low graphic option in game, i have always the same bug.
