Shadows/Textures flickering and shimmering

[Oxmodial]

Hello, I just downloaded the game and I've been having this issue that is ruining my immersion. Whenever I move my character the (although the shadows part gets fixed if I put all shadow settings on high)shadows/grass/trees and sometimes the ground starts to flicker.This is worse during the daytime. I'm running at about 60 fps so that's not really the issue. This seems to be a somewhat common problem and I'm working on tweaking some settings to see if I can fix it.

My specs are:

Windows 7 Home Premium 64-bit (6.1, Build 7601) Service Pack 1
AMD Phenom(tm) II X4 965 Processor (4 CPUs), ~3.4GHz
NVIDIA GeForce GTX 550 Ti - newest drivers
16 GB ram

I've found some examples

Those threads are also is what I'm talking about
I havn't had this issue in any other games, and its REALLY bad and will basically make the game near unplayable for me.
