Digital Foundry have confirmed that the textures are identical to the PS3's and it is the the type of AA that is being used that is causing the blur. Wish they would let us turn it off as jaggies are much preferably to vaseline textures.

You are right Obscene Jester. Ps3 version is using FXAA which is a low cost perfomance anti aliasing technique used by Nvidia that apllies a inteligent blur to every single element on the scene eliminating most of the jaggies! The only side effect is the fuzzy textures and lighting sources that produces! So this is a design choice by Bethesda because RSX (PS3 GPU) cant handle a MSAA which is the standard anti aliasing technique that produces more perfomances hits (although this is the method used by the 360 version thanks to the 10 mb EDRAM on the GPU that makes this aproach a walk in a park to the 360), so they never go release a patch that changes these parameters. The only way this could have been avoided was if the game was developed with the Cell in mind, implementing the MLAA (Morphological Anti Aliasing) that more and more developers are starting to use on PS3 games (like Deus EX). But that requires work so....
If at least they give us the option to turn the FXAA off. I simply dont mind to play the game with jaggies! I just want to see the textures, hdr lighting and the 720p framebuffer on its full shinny potential, that's all!

i second that, it would be a smart choice if they could update the game and remove that cheap fxaa, if youre running on a budget and cant use mlaa then dont use any, qaa fxaa implementation on the ps3 is god awful, i dont understand, oblivion,fallout 3, nv, never used aa on the ps3 and everything looked so sharp, why now? they should seriously consider taking it out.
