hi i have EAH 4870 Radeon HD, when i play Assassins creed 1 the game runs pretty fast with no probs, but the Characters graphics or Shadows are not perfect.......the shadows reflection are not Straight and if you look at the characters ARMS (edges) they are not straight too is this happening to everyone or its something about my drivers? directx? ( i have the latest)

He is wearing a robe... I don't believe the lines are supposed to be straight. If you mean the jaggedness increase your resolution and/or AA.
I think your resolution is a bit low and your settings are not set to high. For me character is fine but some shadows are pixelated .
