Anyone else experiencing this, where certain times in combat, generally when there's a large amount of particles on-screen that the framerate just takes a nosedive? When fighting Bloatflies for example, if you let one get close and successfully hit you with an attack, the resulting screen effect locks up the game significantly for several seconds. Or when fighting raiders inside of the Beantown Brewery, there are certain spots where the framerate will take noticable hits.
There have been a few other isolated spots or incidents where I've seen this and I'm running on a PS4 that is only 2 months old, fully updated and has had 0 issues with any other game.
