Tearing might be coused by AA or resolution different than monitor's native one (if I'm not mistaken...). Also, concerning the various graphich issues, there are unofficial OMEGA drivers for graphic cards (both nVidia and aTI). Basicaly they are the same as official ones but they are specially 'worked around' to increase performance in games. If anything fails, you can try them. Call of Juarez and The Witcher were unplayable on my x1950GT (grey poligons all over the screen) but after instaling OMEGA drivers they run smoothly. (Ofcourse, I take no responsibilities if you encounter problems with them...)
ofT: can't believe none of the shops in Croatia has the game. It's sad...
