As per title, dialogue between characters randomly stutters (other sounds can do the same too) and then characters start to overlap each other whilst dialogue continues. Animations during melee combat also look almost like a power point slide, rather than fluid motions whilst the rest of the game during combat looks relatively smooth and normal.
Youtube link that at least shows the dialogue stuttering I'm mentioning since the file is too large to upload to the site: https://youtu.be/ldU1dnyTWc8
