Disabling NPC Death Animations

[War Raichu]

I really dislike how most of the NPCs in the game go through a static death animation (flying backwards if shot with a shotgun, sinking to their knees if headshotted, etc.), as opposed to SR2 where they would just ragdoll appropriately. Is there a way to turn these animations off? I seem to recall that zombies will ragdoll when killed, but they may be the only ones coded to do so.
