Janky / Jittery Object Animations, after last big patch (and worse performance in general)

Explanation

I think everyone experiences this, not just me, but I am here to make a proper bug report for it. A lot of object animations are really "off". There is a movement in the rotation that's not supposed to be there, its really apparent in with "Triskelion flame 2" hideout decoration.

In-game graphics settings

I've tried nearly every graphical setting combination to make it normal again, but without success. I also tested on stand-alone client instead of steam-client. I am quite certain it's only been like this ever since the last patch, with the engine update. But here are my Graphical settings in game regardless:
