i start to say to you that i'm italian, so some words can be incorrect.
I've a problem with my Palit Geforce gtx275... Excellent vga, but with some games, with some plus but with others less, i see the shadow jagged.
i've set all at maximum, i've tried to set also in the nvidia control panel, forcing the anti aliasing or the anisotropic filter, but nothing.
i see more or less those shadow:
the shadow are jagged and not smooth.. i've also tried to underclock and overclock the core/shader, but nothing.. what can i do??
