Hello, I know this is not the right place, but I only received useless answers, I thought I was just trying it here. does anyone know a solution for this Hitreg in Battlefield 4? it's pretty annoying.

Well there isn't, all you can do is making sure you have a stable internet connection with no issues like package loss or heavy latency (symbols will appear on the right side of the screen if you got this). Also having a decent connection with the server helps. 

Join a server with a low ping, get a good fps, get good internet.

I use killping, has improved hit reg from Australia to Japan and Australia to America. Gives you a 0 ping in game. Does have it ups and downs though.

My connection and FPS are good i have a low ping between 7-20 max and this Problem i have  only in BF4.
