Realistic Death Physics - No Animations Mod
MOD10mm bullets knocking raiders into the air? Deathclaws tossing you around like a tennis ball? Dead bodies floating gently to the ground like rose petals? No more!
Should work with everything that doesn't change physics.
Unlike those mods, this one doesn't edit the actual ragdolls, since the Realistic Ragdoll convertor tool hasn't been (and probably won't be) updated for the new Fallout 4 nifs.
