Massive Performance Regression in breaches since 0.3.1

Since the latest patch, I've noticed a monstrous difference in performance impact while in breaches.

Breaches + Delerium has always negatively impacted framerate but now it's not only worse, but after the slowdown the entire client stays impacted until restart.

This is clearly observable on maps with multiple breaches, by 2-3 breach interactions, the client becomes basically unusable.

I don't have the fastest computer out there, it's a 3950x and RTX 3090, but I've been playing since the start of beta and I've never seen performance impact to this degree.

I have access to another PC with a 7800x3d and 4080 and it's exhibited the exact same type of performance problem.
