Which Version did you grab from the Nexus Page? As other DLCs are Requirements.

I've had this for a few days now and noticed it does seem to work. The enemies are actually missing me a lot, especially at long range and behind cover, as indeed they should. I still managed to get one arrow to the middle of the top of my head, though, when the enemy was standing about 50 meters away, in front and below me, so some of those arrows are still making the same old impossible moves.

As far as I understand it works by limiting how fast the enemies can turn which is really only noticeable in melee, it allows you to dodge leaping power attacks by side stepping etc.

It probably won't make a difference against archery but give it a crack, I'm not sure if the author has done anything else.

If this really works, it removes one of the biggest problems I've noticed. I think I'll give it a go. I really don't think it's very realistic that all the enemies are shooting like a level 120 Dovahkiin all the time. They're also doing it through visual obstructions, like bushes, and some seem to be able to shoot through walls, rocks and trees. Of course, putting up a shield is pointless, when nobody ever hits it with those arrows that magically go around it, to hit you in the back of the head.
