Summary: After playing for a while (it seems to be related to opening containers, but I'm not 100% sure), player and zombie animations (attacking, reloading, etc.) start playing at 1/2 or 1/4 speed and movement starts stuttering, especially sprinting or using a vehicle.

Detailed steps to reproduce the bug:
1) Play the game.
2) Open containers at base or while clearing a POI.
3) Animations (attacking, reloading, etc.) start playing at 1/2 or 1/4 speed, movement starts stuttering (movement is slow but then jumps ahead as if trying to catch up).
Actual result: All player animations and movement, including when using vehicles, seems to run at 1/2 and occasionally 1/4 speed. The only solution is to exit and restart, but this often means abandoning a quest. This is not a framerate issue, as I consistently get 30-60 fps. It is not related to latency (on MP) as I am on a 1 gig fiber connection and pings are usually below 20. CPU usage is not spiking when this happens.
Expected result: Animations play at full speed for the entire session.
