Yesterday I wanted test this myself, So I used this test in two separate group, One with My elite controller, the other with a 3.5 jack controller (Master Chief edition), the first try was at my regular sensitivity which is 3, in both controller there is no noticeable delay, I might have notice here an there a really minimal slowing down in the turn, but is very small and shouldn't affect the aiming, so after I went for a 6 sensitivity, the result were almost the same, again, you feel a small slowdown, now, I never play in such a high Sensitivity so Im not sure how this might affect someone that plays at high sensitivity.
Mind you these were made in a 23 inch led monitor, I will go and try this on a big screen to see if there is something that has to do with the response time of the TV, this test will be conducted on Sunday afternoon and can post my impression on this.
Now, I dont want to call out any poster, or dismiss what they are saying, everybody have a different feel on how they want their aim to be at, but if Anyone here played Halo 3 on release in xbox 360, they had a similar problem, because XBOX 360 controllers suffered from a slow turn that affected greatly the turn right to left and left to right, Im talking about a reduced movement of probably 20%, greater than what Im feeling here so far, You guys can go right ahead and google "Xbox 360 slow turn controller", and there are a good amount of Youtube videos showing how to fix this, I think MS sort of corrected this problem with the newer models of XBOX 360 controllers, but players did play Halo with slow turn for more than a year.
Please post back if you do run a little experiment! Would be super interested to see what you find!
So I did went and the results were pretty much expected, the gun does have a small kickback, and Maybe is me, but I found that getting a headshot with the Pistol was harder than getting one with the DMR. I might look in depth, but Im almost certain that I get killed a lot more with the pistol than with either the BR or the DMR.
