Quick and Dirty mouse fix.

By Uncle Funkle

Fixes a couple pet peeves I have with the mouse, including the vertical sensitivity and smoothing.

THE FIX

IF THE SENSITIVITY IS TOO HIGH/LOW

What does it do?

This makes it so the vertical and horizontal mouse sensitivity are the same. This also should eliminate any potential mouse smoothing or acceleration the game may have baked in. I'll be honest, I'm unsure if it even has the latter two.

These are just standard UE settings tweaks that I'm aware of, I'm by no means an expert on any of this. I just plugged these into my game and it worked, so I won't be of much help on troubleshooting I'm afraid.

THE FIX

GO TO:

%userprofile%\AppData\Local\Stalker2\Saved\Config\Windows

LOCATE FILE:

Input.ini

ADD THESE LINES:

[/script/engine.inputsettings] AxisConfig=(AxisKeyName=‘MouseX’,AxisProperties=(DeadZone=0.000000,Sensitivity=0.01,Exponent=0.100000,bInvert=False)) AxisConfig=(AxisKeyName=‘MouseY’,AxisProperties=(DeadZone=0.000000,Sensitivity=0.01,Exponent=0.100000,bInvert=False)) bEnableMouseSmoothing=False bViewAccelerationEnabled=False

SAVE THE FILE.

If it doesn't work after launching the game, set it to read-only.

OR...

People smarter than me have since made real fixes. As far as I'm aware, editing input.ini is still the best way to kill the mouse smoothing, but here's a proper mod for the vertical sensitivity:

All credit goes to Strangorth[next.nexusmods.com] over on NexusMods. Go show 'em some love.

IF THE SENSITIVITY IS TOO HIGH/LOW

AxisConfig=(AxisKeyName=‘MouseX’,AxisProperties=(DeadZone=0.000000,Sensitivity=0.01,Exponent=0.100000,bInvert=False))
AxisConfig=(AxisKeyName=‘MouseY’,AxisProperties=(DeadZone=0.000000,Sensitivity=0.01,Exponent=0.100000,bInvert=False))

Change the Exponent values (shown above in bold) to a higher or lower number depending on the sensitivity range you desire. The in-game mouse sensitivity options will still work, so don't worry about fine-tuning it too much in the config.

If that didn't work for you, you instead need to go to:

%localappdata%\Stalker2\Saved\GameSettings

and edit: AppliedSettings.cfg

The Fourth and sixth line (MouseSensitivityCoef and AimMouseSensitivityCoef) are your in-game sensitivity settings. Editing them here will allow you to go both higher and lower than the in-game slider allows (in my case I needed them to be lower.) Keep in mind though that if you later change your sensitivity in-game, you WILL lose these settings and need to change them in the config again!

this shit doesn't work at all lmao in fact it makes your game mouse sensitivity absurdly higher regardless of what you d o to senstivity and exponent

@Ygdrad, Good shout man! Knew it was only a matter of time before the real geniuses came in. Thanks for lettin' us know

This does not work. The difference in sensitivity is baked deeper in the code and this setting does not manage to override it. This mod actually does the trick. https://www.nexusmods.com/stalker2heartofchornobyl/mods/57?tab=files

@unclefunkle it works, but u need to change DPI in mouse. Ingame sens doesnt work(ty cap)

МІСТЕР ПРОПЕР ДНР 22 Nov, 2024 @ 4:54pm

thanks a lot, worked great for me, input lag with frame generation is almost not felt, much better than before

Uncle Funkle [author] 22 Nov, 2024 @ 2:21pm

@LikeMySoul, Ooooh, that sounds awesome if it works. Let us know your results!

LikeMySoul 22 Nov, 2024 @ 1:08pm

Anyone testing bUseRawMouseInput=True for XY sens sync?
In theory - this option should bypass engine settings and use only mouse's base DPI\CPI

Awesome! Thank you!

So it wasn't just me! I was attacked by a dog and the vertical mouse sensitivity made no sense.

Uncle Funkle [author] 21 Nov, 2024 @ 1:26pm

@jinping thought pixie dream girl, I originally had the exponent value at 1.0, but that made the sensitivity even higher. After further experimenting, I think 0.1 might actually be the floor for the exponent setting as far as lowering the sensitivity. That means as far as I'm aware, the only way you're gonna get a lower sensitivity in-game is by editing AppliedSettings.cfg or making a separate DPI profile just for the game. Neither of which are attractive options sadly.
