I've been playing Halo for years on and off and somehow it was just tonight that it dawned on me to turn off the rumble in my controller.  Immediately, I got way, way more accurate, especially on the DMR and needler rifle.  Anyone who plays Halo on a regular basis knows that those are the defining weapons in multiplayer that determine whether or not you can play effectively.  What I can't get past is how incredibly stupid I have to be for the idea of turning off controller rumble to only now dawn on me.  I'm also making this thread for those with heads of equal thickness and density who, like me, are dumb enough not to have realized just how much this can improve your game.  I was wondering what people were doing to be so much better at the game than me, and I guess I have my answer.  I'm by no means the best at the game, but I find that I'm no longer coming in last on my team.

I say this with no sarcasm, but yes, I remember when I realized to do this in Halo 3. It was truly a game-changer in multiplayer, particularly with the Spartan Laser.

I don't think that makes you a dumbass but ok.

Hmm that's weird. I don't play Halo or anything, but I would think that a slight rumble has no impact on aiming with a thumbstick. You learn something new everyday.
 
I also don't think this makes anyone a dumb. Now, I'm not saying that you're not a dumb-ass. You could very well be one. All I'm saying is that this has nothing to do with it.

I eventually got tired of how hard rumble rumbled.  It's kinda-sorta okay, but I frequently find it distracting now.  I remember back when I thought it was cool, lol, and it still sorta is.

But gameplay first!  Parlor tricks second.

Hmm... I'm by no means bad or great at Halo, but I play with rumble on. Part of me wants to turn it off to see if I get better... but the rumble of my controller also alerts me when I'm being hit, so maybe it's best I leave it as is.

On the contrary , with no rumble I get worse ...... I just like having the feedback and the rumbling doesnt shakes the controller to that degree ... but to each his own I guess

Maybe I should try it.  I suck ass at FPS games.  Maybe I will go come complete garbage to just garbage.

Need to give this a try, thanks!

I wonder if this would help in Call of Duty any... I'll try it out!

I turned off rumble the minute it was invented. What was that, the PS2? It was instantly annoying to me and I am just happy the option has always been there to turn it off.

I think I am in fact stupid.  However, that's because I've sunk hundreds, probably over a thousand hours into Halo 2, 3, and Reach without even thinking this might help.

then I must Truly Be a genius...upon first using rumble on starfox 64 I opted to never use it again and turn off rumble in my general settings on xbox so every game I play never rumbles...oh and then I open my controllers and remove the rumble motors making them lighter to boot.

I need to try this and see if it makes a difference.

er...I didn't notice turning off rumble makes so much difference
 
I just turned it off thinking it is annoying when playing rocketfight...

I never even considered this. 
 
I like rumble way too much to turn it off, though. Interesting find!

Turned it off.  Didn't really notice a difference, but I also didn't miss the rumble, even a little, so I'm leaving it off.

Where do I turn it off at?  
 
I looked before but couldn't find it, turning off rumble really really saves on batteries and charging.

Never played with it on in games where FPS precision is key. Works well in third person single-players that rely on atmosphere, but it's annoying as hell when you're relying on being able to move with precise accuracy. 
 
@ShaneDev: XMB -> Settings -> Prefferences -> Vibration. 
 
 
Also, it's good for your battery life.

Speaking as someone who has been playing without rumble since Halo 2 -- welcome to the club!

" I turned off rumble the minute it was invented. What was that, the PS2? It was instantly annoying to me and I am just happy the option has always been there to turn it off. "

Rumble hasn't really impacted my game, so i'm leaving it on. I like it.

It's always a really alien experience to hold a dead-weight controller in my hands when rumble turns off. I guess I'm not willing to sacrifice that immersion just to bag a few extra kills.
