Hello forum!
This will be my first post here, so please do tell me if anything is not in order/missing, I'll try to be as complete as possible.

(note in advance, I -do- have screenshots, but am not allowed to post links. Please let me know how to share those for clarification)

Since recent I have a new desktop computer, and decided to install fallout 3 on it with a load of mods.
PC config:

The version I run is 1.7, with DLC, and I just tried installing the unofficial patch linked in one of the sticky posts here (didn't help).
The setup is the same I have used on my laptop (which ran just fine) and my previous desktop before that (which also ran just fine).
My base install is the collectors edition (lunchbox).

The problem I am suddenly experiencing is blurred textures on the weapons/hand and in 3rd person under a certain angle on the head/shoulder area of the character or even more including the surroundings.
These blurs are not just on there, but they are on that general area of the screen as text/hud/anything in that area is blurred.

Most likely this is caused by something related to the mipmaps, as I already found out by two afternoons of searching the web.
There isn't any direct information about this occuring in fallout 3 though, so I used some instructions that seemed related.

Something I found was to put the mipmap/AA in CCC all up to high, I already have this so that doesn't fix it.
At first I didn't have the option to change the mipmap settings in CCC, where it was mentioned to change "TextureLOD_NA and set its value to 0" in the windows registry.
I did that, it worked. Next day it's blurred again and that 'trick' doesn't work anymore.

I've also tried different drivers for my graphics card, I started with the most recent (CCC 12.10) and have now tried to use the 12.11 beta hoping that might work, it doesn't change a thing.

I've tried different graphics setting both in the game and on my graphics card, ranging from lowest to highest, where nothing seemed to help.



Further information I can give:

The mods are not the issue, I've tried it both with them on and off to see if they bug up somewhere, that's not it.
Once during browsing for a solution, I randomly decided to just start the game up, it looked good, double check that by restarting it, back to blur.
The blur gets less if I aim for the ground and get as little space between my viewpoint and any background that I may be looking at.


I'm now going to try the only thing I haven't yet, which is re install the game.
I don't know if that will do anything, but I'll update this post asap.
if anyone here might have ideas left or even experienced this themselves, I'd like to hear about it
And as said at the start, if anything is missing or not up to rules/regulations or just plain unclear, please do tell me.

Thank you in advance for taking the time to read through the long post and/or thinking along.
