Realistic Ragdolls & Force
Realistic Ragdolls & Force is an extremely popular Skyrim mod for PC that's made its way over to the Xbox One.
The premise is pretty simple. The mod reduces the extra force the game applies to ragdolls to give it a more realistic look and feel.
It also makes it so bodies bend and twist in a more realistic fashion. For instance, arms will bend behind the back. It makes for better looking combat.
You can get a feel for the changes in the video below.
Unfortunately, it's not available for the PlayStation 4.
