Laggy ragdoll physics

[Voynich]

Is anyone else having this issue? Everything else in the game runs fine, but the second someone gets knocked out, the ragdoll animation becomes a slideshow. I've tried importing the save, deleting the data folder and re-verifying the cache through steam, using different saves, going to different locations (as in less populated ones). Nothing seems to make it better.

My PC's hardware shouldn't be the problem:

intel i7-2600k @ 4ghz
GeForce GTX 680
8 gigs of RAM

I understand it's in alpha, and this may just be another bug to deal with, but it doesn't seem like many people are having this issue, based on all the videos I've seen. Any ideas?

edit: after verifying the cache one more time through steam, the problem seems to have gone away. If it comes back I'll bump this topic, until then please ignore
