Scarlet Nexus – How to Adjust Mouse/Gamepad Deadzone and Sensitivity

A simple and quick guide to changing Scarlet Nexus’ Deadzone and Sensitivity. There’s also a setting to turn off Mouse Smoothing.

Adjusting Deadzones and Sensitivity

Scarlet Nexus comes with a rather high Deadzone for both Gamepads and Mice by default, which can be annoying for some users, and there is no way to adjust them. The developers only allow us to change the Camera Speed, but no Deadzones or Sensitivity.

It is repairable by modifying the Input.ini file yourself. The Input.ini file can be found at:

%LocalAppDate%\ScarletNexus\Saved\Config\WindowsNoEditor\

Open Input.ini and paste in the following:

[/script/engine.inputsettings] AxisConfig=(AxisKeyName="Gamepad_LeftX",AxisProperties=(DeadZone=0.250000,Sensitivity=1.000000,Exponent=1.000000,bInvert=False)) AxisConfig=(AxisKeyName="Gamepad_LeftY",AxisProperties=(DeadZone=0.250000,Sensitivity=1.000000,Exponent=1.000000,bInvert=False)) AxisConfig=(AxisKeyName="Gamepad_RightX",AxisProperties=(DeadZone=0.250000,Sensitivity=1.000000,Exponent=1.000000,bInvert=False)) AxisConfig=(AxisKeyName="Gamepad_RightY",AxisProperties=(DeadZone=0.250000,Sensitivity=1.000000,Exponent=1.000000,bInvert=False)) AxisConfig=(AxisKeyName="MouseX",AxisProperties=(DeadZone=0.000000,Sensitivity=0.07,Exponent=1.000000,bInvert=False)) AxisConfig=(AxisKeyName="MouseY",AxisProperties=(DeadZone=0.000000,Sensitivity=0.07,Exponent=1.000000,bInvert=False)) bEnableMouseSmoothing=False

Epic’s default values for UE4 are as follows. I also added a configuration line to turn off Mouse Smoothing.

I set every Deadzone for the Gamepad to 0.000000 and increased the Gamepad LeftX and Gamepad LeftY Sensitivity to 2.0. This may be a little high depending on your Gamepad, and I tested it on a newly purchased PS5 DualSense Gamepad. By default, the Left Stick requires a significant amount of input before you can begin walking or running.

Also, after editing Input.ini, make sure to set it to Write-Only, or Scarlet Nexus may replace it with an empty file again at some point.
