how to sharpen environment shadows?

[MTL]

Ok, ive touched almost every shadow setting in the UTEngine.ini and cannot figure out how to make the environment shadows not blurry!
Are the shadows "cooked" on like that? I even disabled LightEnvironmentShadows and the shadows are still there?
I would like sharper non blurry shadows on the environment for possibly more performance with shadows on, is this not possible? I think the game would look better with sharper shadows too...

UT3 tries to emulate real time lighting as much as possible. Take a look at your own shadow in daylight, its not solid is it :P So no, nothing you can do here.

yeah, but funny thing with the unreal engine3 is that i CAN sharpen dynamic player/vehicle shadows by setting ShadowFilterRadius=0
i dont know what setting modifies the environment shadows
