is it just my ps3 controller , or has anyone else suffering from delayed motion as far as left or right motion on the weapon is concerned?

Sometimes mine refuses to move left or right for 1-2 seconds, but that doesn't happen often, and when it does, its usually only once.

yeah , do you think its the controller or the software?

I would guess software, as I don't recall it happening in other games. I have dropped my controller a lot of times, and if it doesn't happen in other games on mine after all of that, its probably a durable controller, so the unresponsiveness is likely software.

yes , likewise, mine is very responsive in the call of duty series and i have absolutely no issues. so i guess its the software and will have to wait until a fix is released or get used to it. Thanks brother!
