Well Honestly, you have to look VERY closely to see differences this HD Patch brings. It's all in the finer details, like extra grain on wooden doors, less blurry tables, sharper lines on some weapons and shields etc.
It's best to use it in conjunction with the Skyrim HD 2K textures mod. That mod Makes a HUGE NOTICEABLE difference, combined with this it's about the best Skyrim will and can look at the current moment.
I am in process of creating a huge Skyrim Uberfication Guide with recommended mods, installation instructions, load order, comparison screenshots etc.


I immediately noticed it on my bow texture.
