(This post is an addendum to the Nolt post here)
After playing on the latest update, I've noticed huge performance issues that did not exist just a few days ago. I'm having large persistent framedrops throughout the match and big drops on large hits and 'purple' screen effects. Additionally, two Forsburns on screen is a performing HORRIBLY, which was not a problem in the past.
The annotated video linked below should hopefully show it off. I know it might be hard to guage using a 60fps rendered video but the slowdowns are frequent and very noticeable. I play the game at over 200+ FPS so when the framerate drops significantly, it feels terrible. You should at least be able to notice the KO screen drops.
