I just had a second match in a few days that I just had to straight-up close app on because the framerate took an absolute shit.
Before the latest patch when playing as Predator on PS4 the game would often freeze for several seconds, but now it's even worse. Instead of just freezing and then going back to normal, which is bad enough as it is, the framerate literally drops to 1 or 2 frames per second and just stays that way. I was destroying the fire team when it happened (and they were actually talking to, so it was fun!), and after that it just never went back to normal. I wasn't even in a fight but I had no choice but to close the game because I couldn't do anything, let alone aim, fight, run etc. It became a slideshow.
More than anything else they need to get on a fix to that asap, because it's literally rendering the game unplayable when it happens, and now it's no longer just been a one-off occurrence.
