Hit reg and crashing, can also be from malicious actors.
I don't know if rogue devs or 3rd party trolls. But, it happens in all games too. alot of it has to do with how good you are playing. Now I know the argument has been made in the past that its the cheat detection, and it could be and maybe it puts some machines over the top when it starts monitoring in game. But when I'm on vpn it happens more, a direct x error, or just a crash to desktop with no comment. I thought I fixed my crashing by limiting my frames. but today I got a crash for the first time in weeks even with vpn off. And it happened to be when I was dominating the server, which is rare for me. Coincidence? Never was in past bf's either.
So add to the fact that some guys just seem to take massive damage and insta kill you without even looking at ya. Which alot of new comers are coping with by attributing it to hit reg and blaming EA, which they were probably brainwashed by the cheaters themselves to say, ironically. But add to that the fact they can just crash your game and boot you from the server. Wow. When is the gov't going to do something? when is society going to stop pretending like its not happening? God help us.
