My husband and I both have experienced on-and-off latency with our key presses. Sometimes the game will stop responding to keystrokes for several seconds and then resume.
I don’t get seconds, but sometimes I get like an eighth of a second of keyboard input lag for a second or two, as if my ping went up but only to my character, enemies don’t rubber band or anything. This is the only game I’ve ever experienced with that.
Yes, mostly during Hight Intensity missions when a lot is going on. The game seems to have trouble keeping track of key presses and registering hits.
