&quot;It takes a bit more than just changing MouseX/MouseY settings to fix the input problems there are new multipliers in place that modify mouse input significantly.

Here are the settings that need to be changed;

in UTInput.ini:

[Engine.PlayerInput]
LookRightScale=0.000000
LookUpScale=0.000000
bEnableMouseSmoothing=False
...
Bindings=(Name=&quot;MouseX&quot;,Command=&quot;Count bXAxis | Axis aMouseX Speed=2.0&quot;,Control=False,Shift=False,Alt=False)
Bindings=(Name=&quot;MouseY&quot;,Command=&quot;Count bYAxis | Axis aMouseY Speed=2.0&quot;,Control=False,Shift=False,Alt=False)
... (
Bindings=(Name=&quot;LookUp&quot;,Command=&quot;Axis aLookUp Speed=+25.0 AbsoluteAxis=0&quot;,Control=False,Shift=False,Alt=Fals e)
Bindings=(Name=&quot;LookDown&quot;,Command=&quot;Axis aLookUp Speed=-25.0 AbsoluteAxis=0&quot;,Control=False,Shift=False,Alt=Fals e)
...
Bindings=(Name=&quot;GBA_TurnLeft&quot;,Command=&quot;Axis aBaseX Speed=-40.0 AbsoluteAxis=0&quot;,Control=False,Shift=False,Alt=Fals e)
Bindings=(Name=&quot;GBA_TurnRight&quot;,Command=&quot;Axis aBaseX Speed=+40.0 AbsoluteAxis=0&quot;,Control=False,Shift=False,Alt=Fals e)



[UTGame.UTPlayerInput] &lt;- same thing in this section as playerinput.
LookRightScale=0.000000
LookUpScale=0.000000
...
Bindings=(Name=&quot;MouseX&quot;,Command=&quot;Count bXAxis | Axis aMouseX Speed=2.0&quot;,Control=False,Shift=False,Alt=False)
Bindings=(Name=&quot;MouseY&quot;,Command=&quot;Count bYAxis | Axis aMouseY Speed=2.0&quot;,Control=False,Shift=False,Alt=False)
...
Bindings=(Name=&quot;LookUp&quot;,Command=&quot;Axis aLookUp Speed=+25.0 AbsoluteAxis=0&quot;,Control=False,Shift=False,Alt=Fals e)
Bindings=(Name=&quot;LookDown&quot;,Command=&quot;Axis aLookUp Speed=-25.0 AbsoluteAxis=0&quot;,Control=False,Shift=False,Alt=Fals e)
...
Bindings=(Name=&quot;GBA_TurnLeft&quot;,Command=&quot;Axis aBaseX Speed=-40.0 AbsoluteAxis=0&quot;,Control=False,Shift=False,Alt=Fals e)
Bindings=(Name=&quot;GBA_TurnRight&quot;,Command=&quot;Axis aBaseX Speed=+40.0 AbsoluteAxis=0&quot;,Control=False,Shift=False,Alt=Fals e)


I am not particularly sure about what all of the settings in [UTGame.UTConsolePlayerInput] do, as they are kind of convoluted ... but it wouldn't hurt to make all ViewAccel_* settings = 0.0f &quot;


Iv'e found that the game feels completely different after doing as suggested in the tutorial, and frankly im suprised why Epic has implented mouse acceleration in the game by default, and even more suprised that there is no option to disable it via UI, and even through the inis as you can see its far from being simple like turning &quot;True&quot; to &quot;False&quot;.

In my opinion Epic must add an option to completely disable mouse acceleration in the next patch, the game feels so good without it.

Dont forget to also disable it with:
bViewAccelerationEnabled=FALSE &lt;- disable mouse accleration

Remeber to double check you ini's people.
