Forum:Help: A command to increase distant water detail?

Hi. Sorry for my poor english) I'm running fallout 3 with a HD4870. Almost all settings are to maximum. I have noticed that distant water doesn't look as near water. It's like just a blue polygon and there is an ugly line separating "near water zone" and "far water zone". I'd like to increase the distance that water showns great. Note that I only want to change the WATER detail distance, not every element in game (this would drop too much my fps). I've tested the "unearwaterradius" command, but this is not the answer. So, does anyone know a command for this? Thanks.
