E.g. there is same shimmering of shadows in such a great game with huge budget Total War Shogun 2, even in game menus. I saw it present in ArmA2 too I think.
Hopefully they use different technology in the sequel. E.g. BF3 does not have shimmering.

Visual shimmering with shadow maps is directly related to the shadow map texture resolution, and the size of objects as they are viewed from the light. FPS games with not too much distance to draw and objects filling a lot of screen space are optimal for this, while big landscapes with tons of small objects like trees are the worst situation. It´s unfair to compare BF with CoD. Even Total War scenery is a lot smaller than CoD.
ArmA2 uses a combination between shadow maps ( for near landscape ) and stencil shadows, for soldiers and vehicles. Stencil shadow is the alternative to shadow map. It has no shimmering at all, but it is slower if you have tons of objects to cast shadows, the shadow can´t be easily blurred and shadows can´t be calculated trough alpha objects, like trees or clouds.
What we have its not a so bad compromise for a so huge landscape, if we want to see shadows so far as we have.
