:'( why do l hear this so much?!, people like it better. But really mine jams ALL THE TIME!!! I was BEAST when it didnt jam but then l started jamming ever since about a year ago!! whyyyyy
It's lag in my experience. either you or the host.
Connection issues cause a spread of shots to try to fire all at once (Shotgun M9/AK style) to prevent that the gun jams up because if a FAL or G-MAL fired all at once the opponent is dead. No questions asked.
How do l know if l'm lagging?! Or how to fix?!
I could be wrong on some of this. Not all of it though.
As for fixing the first two...
A better connection: Are you using wired or wireless? If you are using wireless that explains everything or should. Wireless has issues, think of the amount of time data flies through the air to your PS3.
If wired? Maybe the wired cable is broken or split somewhere? A new wire could help.
If those two fail, maybe your connection is not very good and you need to call your provider to clarify it's working properly.
or maybe it's the one I can't help you with being the losing data thing. I actually lose data too sometimes and have no idea how to stop it happening apart from maybe just changing my provider. calling your provider may help but it certainly didn't help me.
