Can't be bothered to quote everyone's posts, but in response to the previous posters...
I have 'Treasure Map IV' and there is still nothing at the location it describes
I also have a 'Treasure Hunters Note' that now only shows garbled text, cannot be removed from inventory and I have no idea which quest it relates to (bloody radiant system, lol)
I still get FPS drops in certain places - Helgen Caves, Deep Forests etc etc, but the overall experience is significantly better. The most noticable thing is the reduction in stuttering when walking around cities. Whiterun is nearly smooth now, previously I had 2-3 second 'hitches' when going up/down steps etc.
Ash piles of named characters do not 'clean-up', and arrow cleanup is dodgy at best.
Enemies still lose ownership of their weapons upon death, preventing them from cleaning up. I provided Bethesda with a fix for this, so here's hoping they implement it, or something similiar, in 1.5
All the tutorials came back for me as well - but I can live with that
