Describe the Bug

This issue arose after PR #1973

Loading into the game and going to Hunter's Dream, the Hunter's Nightmare and especially near the Suspicious Beggar in Forbidden Woods, there is noticeable stutter when rotating the camera or looking in certain directions. The camera movement itself seems uneven, as if the analog stick speeds up and slows down again. The effects of the Abhorrent Beast introduce extra stutter, though it's momentary. This issue did not exist on previous versions. I have tested multiple times with older releases and have confirmed this is, indeed, a new problem. General performance does not seem to be affected that much when not stuttering, but the problem is the slowdowns don't just happen when looking at a distant sight or something like that. There is a constant stutter. It's not enough to make the game truly unplayable, but it is very jarring.
Any time the camera is rotated, this stutter occurs, even in the Hunter's Dream, which is the "emptiest" map I could think of.

Reproduction Steps

Loading into the game, the stutter and jittery movement are constant.
