I will get the texture ESM files soon, I only have 896 vram so I will grab if for the sake of it but not massively into using it, I use selective texture mods at the moment. I am pretty happy with the look I have got from Flaura mod/ground texture mod/clothing mod without causing any performance hit at the moment anyway.
They have deff stepped up the game with these releases and patch. I can now (dual core 3gig) play Ultra with shadows medium and ugrids set to 7 for farther draw distance, some minor micro stutter and that's all. Prior to 1.4 I had 20 fps in some cities and all set to high only, on horse I would get jolts and spawn pauses and so on (I could tell when AI was spawning as I would get a large jolt pause prior to it), they have finaly got this up to shape as it should have been release day, for me its like playing on a quad upgrade with a game that struggled on my "old machine" in terms of how it feels.
BTW an important thread is posted on how you can use the new HD texture DLC pack without it overwriting loose file texture mods (so texture mods over write the HD pack and use it as a base) here:
