Super sledge no knockback

[S.T.A.L.K.E.R]

Knockback perk doesn't work

unless it was changed or something

I has same problem, but with Sledgehammer (it does have knockback weapon perk also)
I played few days, killing enemies with just sledgehammer. None of those humanoids will be thrown away by my hammer :/

[plenty]

I'm quite sure that in FO it should have knock-back on a critical hit only. Was considered too powerful otherwise.

Knockback is the ability that a weapon may have to knock your target down while at the same time pushing it over the ground, be it because of the perk of that name or the type of damage they inflict.

The following weapons have the Knockback perk, triggered by a critical hit only:
Super Sledge
Sledgehammer
Louisville Slugger

I do score criticals, even the ones that say they've been knocked down, still won't send them flying

Maybe STR roll is also required? As with heavy handed? I've tested super sledge today (with a Silent Death char), most crits caused knockback.
