Characters bobbing up and down

[nognow]

All NPCs start to bob up and down whenever I look at them from close range. Zooming in on them causes it from any distance.

In the video, I'm obviously using mods, but I tried vanilla (with the exception of NVSE related mods) and it's the same thing

Is your framerate over 60 fps?
The more your framerate is above 60 fps, the more likely you'll see this problem.

yes, it is.

capped at 119 with Gsync.

I'll play around with various fps and vsync settings and update.

that's indeed the culprit.

lowering the refresh rate to 60 did the trick.

but I don't want to loose out on half my fps, any known fix to this?

No idea how to fix it, but you can disable Leg IK in the Fallout.ini. Search for the "Leg" and you'll find it.
However, by disabling that, actors will no longer adapt their leg position to the terrain.

I just looked through all INI files, there are no entries with the word "leg"

There are a bunch of settings under FootIK but I see nowhere to disable it, anyway I've had what's described here and switching off FootIK via TFIK in console didn't help so I left it on.

I apologize. Yes, "Foot", not "Leg".

Also, according to NVTF's author:

Solution #1:
Make sure that your in-game framerate is capped below 120 FPS. Better use some fps counter to double check if it really is below 120.

Solution #2:
That is a trade off between player foot dynamic placement efficiency and the absence of foot bouncing glitches for NPCs. It eliminates NPCs bouncing glitches almost entirely, but also makes player dynamic foot placement work slightly worse.

Set these lines in [FootIK] section using either "FalloutPrefs.ini" or "FalloutCustom.ini" to the following values:
fOnOffGain=0.01
bFootPlacementOn=0
fPelvisUpDownBias=0
fPelvisOffsetDamping=0
fOriginalGroundHeightMS=0

Solution #3:
[RagdollAnim]
bFootIK = 0

Try capping your framerate to something lower than 120 fps.

Capping the framerate doesn't help (I had already done it), disabling bFootPlacementOn did the trick; no need to touch the rest.
