One of the main offenders we found when it comes to the hitching and like the stuttering that people have been seeing is the new physics engine that we're using for the game.

It's called Chaos, which is a fitting name for, you know, how production for this update has been going.

When a game is making too big modifications of acceleration physics or doing fast physics operation, the physics engine would cause buffers to constantly be rebuilt, and that's a problem.

Epic are aware of the underlying problem, we reported to them, but they don't currently have an ETA on when they'll have a fix for this, but we've implemented our own fix, so we have our own solution to fix this problem for now.
