ARMA 3 Ragdoll used to be quite good!!! The characters simply dropped straight down just like footage from WW2 D-day landings, and looked heavy like they possess real mass...
Now when shot they seem to twitch and fling all over the place, sometimes bending in half and head butting the floor then immediately standing up straight again. Just yesterday I shot a soldier on the lower floor of a two storey building, and he flew up through the ceiling and ended up swinging from the ceiling (the next floor up) by his elbow :-s
They're acting as if they've been hit by a cannon ball charged with 6000 volts.
The old ragdoll was better by simply dropping in the direction that the character was travelling. {F21448}
