I also have this problem even when collecting crates if the are four items in the crate there is a frame freeze on the PS4 (non Pro). This seems to be a performance rather than connection issues. During game play I tend to see the frame freeze when there is a large number of players and gun fire on screen which generally lead to death and a huge amount of frustration.
Changing options to reduce graphic / film effects makes no difference
I have circa 30Mbps download and circa 8Mbps upload on my broadband.
I have a HDR Samsung TV
Connected to my local England Ping Site response is 20ms which is the best possible
I also played the Beta Test extensively and saw not Frame Freeze with the same set up.
Is this within acceptable limits?
