Alternate Mouse Fix

Other bioshock mouse fix guides didn't work for me, this is what i did and it worked.

Introduction

There is another guide on steam, I tried it and it didn't work because it's wrong. This guide fixes the mouse sensitivity being too high; and the mouse being sporadic because of sensitivity, acceleration, and smoothing.

Using information and solutions pulled from google, followed by tedious opening and closing of the game as I tested every change one at a time, I have found what does work and doesn't work.

I can namely thank this post

This guide mainly takes what he did and post it on steam to make it more findable.

Find your Application Data\Bioshock folder.

You may have to reference other guides on how to find this folder, but there are three things you need before proceeding:
1) enable your computer to show hidden files.
2) enable your computer to show file extension.
3) locate User.ini, which is in your Application Data\Bioshock folder.

Windows XP
C:\Documents and Settings\[Username]\Application Data\Bioshock
C:\Documents and Settings\[Username]\Application Data\Bioshock2
Windows Vista, 7, 8, and 10
C:\Users\[Username]\AppData\Roaming\Bioshock
C:\Users\[Username]\AppData\Roaming\Bioshock2

Edit the User.ini file.

Fix the sensitivity issue.

Open the file, and throughout the entire document and replace anything that has

MouseX=IF_MOUSE_LOOK_ENABLED Count bXAxis | IF_MOUSE_LOOK_ENABLED Axis aMouseX Speed=2500.0
MouseY=IF_MOUSE_LOOK_ENABLED Count bYAxis | IF_MOUSE_LOOK_ENABLED Axis aMouseY Speed=2500.0

to 1200. All 10 entries. This 2500 number is what makes the mouse way too sensitive and lowering the number helps significantly. Has no effect on the menu screen though.

Turn off mouse smoothing.

Find all 9

W=MoveForward

and replace it with

W=MoveForward | set Engine.PlayerInput MouseAccelThreshold 0.0 | set Engine.PlayerInput MouseSmoothingMode 0

and it should be in a single line, don't break it up into two or more. What this essentially does, is every-time you move - mouse smoothing is turned off. Mouse smoothing gets turned back on by the game several times so that's why we're doing this.

Save and your done.

What not to do

- Do not set your in-game sensitivity to 1. It's bugged, not for everyone but I just don't recommend it.
- When in-game, if you reset the "custom key bindings" to "default", then you will have to do all of the above again. I suggest you make the User.ini file "read only".

This isn't helpful but I didn't have this issue.. My mouse is a cheapish "gaming mouse" and it has physical +/- buttons i can press to slow or speed up my cursor speed.. I did have to adjust it every now and then. I wonder if that saved me a headache :p

computers were around long before this game was made. this is unacceptable from them.

This is one of the more stupid and fucked up .ini files I've ever seen. Understand the game is old but jeez. Thanks for the guide on this. Much appreciated.

Just wanted to note that this fix seems to still work! Thanks for the guide!

I appreciate the guide, but every time I loot search a container or a corpse, my mouse sensivity goes all crazy again until you look away from the container/corpse, and then it's all fine.
I usually play games using a low sensitivity (Didn't set it on 1 on this game), but I doubt if there could be a fix for this issue.

again, thx. this guide is pretty much prerfect, actually. you even left a suggestion to make the files 'read only', which was very helpful, because the game kept crashing when exiting.

[vran]

ah nvm sorry, i got this. had to relaunch the game like 20 times until i got a number of 660.0 on the XY mouse speed for the sens i wanted. yeah its a mess, but im about to finish the game anyway.

[Discarded]

It's been a few years since i did this. I remember that it worked for me at the time. I'm not sure it was ever perfect like on COD games or portal though. it's pathetic that they call this a PC game with those mouse controls to be honest.

[vran]

the commads seem to make sense, but every time i load and press w, the sens actually increases. also it feels kinda clunky. you sure this works the right way?

[vran]

thanks man, also changed my dpi to adjust to a really specific sens
