Dead Space 2 Mouse Fix

What is this?

This fix makes Dead Space 2 use raw mouse input without any additional smoothing or acceleration. It works with VSync and high frame rates and is easy to install without having to fiddle around with FPS limiters or config files.

You can download the fix from PC Gaming Wiki here.



Even though the mouse controls in Dead Space 2 are better than in the first one, it still suffers from many of the same issues. Most notably, it has negative mouse acceleration and a sensitivity that is dependent on the frame rate, which leads to inconsistent movement when the performance is not stable.

This fix circumvents those problems by acquiring raw mouse input and injecting it directly into the game’s camera functions.


  • Raw mouse input independent of FPS or VSync
  • Reasonable sensitivity range
  • Same sensitivity in each direction
  • No dead zone for slow movement
  • No additional smoothing or positive/negative mouse acceleration
  • Improved mouse cursor
  • No automatic camera re-center
  • Configuration via the ingame settings as usual
  • Simple installation and usage without any external configuration


Supported Versions

Important: This fix relies on the latest, fully patched executables of the supported versions. Older versions or ones that otherwise have been tempered with might not work.

  • Origin/Retail
  • Steam


The fix does not make any permanent changes to the game or the system and can easily be removed (see below).

  1. Extract the file dinput8.dll to your main game folder*. For example: "C:\Program Files (x86)\Origin\games\Dead Space 2\".
  2. Start the game like you would normally, for example directly through Origin or Steam

See *Loading Other Fixes/Mods/Injectors for information on how to use the fix with another fix, mod or injector that uses a DLL file with the same name.


  1. Remove or rename the dinput8.dll from the folder of the game.

How To Use

After the installation the fix does not require any additional treatment. Just launch the game as usual.

To change the sensitivity just use the ingame settings like you would normally. The fix also incorporates the x- and y-axis inversion settings.

Loading Other Fixes/Mods/Injectors

To increase the compatibility with other fixes, mods or injectors that are also using a dinput8.dll, this fix offers a remote loading feature of additional DLLs. This can be done in two ways:

  • File method: The fix DLL will automatically load a DLL that has the same name as itself with the postfix _Remote added to it. For example dinput8_Remote.dll. Just rename the DLL file you want to load accordingly. This is the simplest way if you only have a conflict with one additional DLL
  • Folder method: The fix DLL will also automatically load all DLL files regardless of their name in a sub-directory that has the same name as itself with the postfix _Remote added to it. For example dinput8_Remote. Just create a folder with the corresponding name in the install directory of the fix. This is the only way to load multiple (conflicting) DLLs

Note that there might still be compatibility issues between the different fixes, mods or injectors that have nothing to do with the loading process.

Additional Information

What You Should Know

This fix is essentially a hack and relies on the layout of the specific executable. There may be crashes or unexpected issues. Feel free to provide feedback so that the problems can get fixed.

Since this fix consists of an executable DLL-File, I could have put any harmful shenanigans in there. You just have to trust me that the file is clean.

If you do not — and why should you — feel free to use a meta online virus scanner like VirusTotal to verify the file. Be aware however, that because the fix uses “hacking techniques” such as injection and hooking, it could trigger anti-virus software without being harmful.

Known Issues

The fix currently does not work with the alternate .exe file that removes the preorder/promotional DLC from the Steam version of the game.


I would like to thank Kaibz for his detailed bug reports and testing for the v1.0 version of the fix.

Version History


  • Initial public release


  1. I have always played games with very high sensitivity settings and it saddens me that these Mouse Fixes change the sensitivity range, so that I cannot use the fix and play… I wish you could someday revert the sensitivity range change so that players like me could still play the game with the fixes. I noticed the same issue both in Dead Space games aswell as Metros.


    1. Since the rationale for the Dead Space fixes was the same, I will just for the sake of completeness quote what I wrote in my reply to your Metro comment:

      “The goal was to adjust the range in such a way that it is about right for the majority of players. Unfortunately you have to make a decision on what that range is. When you have a slider without an option to enter precise numbers, you cannot make the range too big, because then it will not be precise enough for slower sensitivities. I tend to make the ranges a little smaller, because it is much easier to set higher ranges by adjusting the DPI settings of the mouse than the other way around. Additionally, very high sensitivity players are a minority.”

      My advice again would be to try adjusting the sensitivity in the config file, since that allows you to go above the boundaries. Otherwise you could adjust the DPI on your mouse if that is possible.


      1. I guess I got no other options then but to use the config file and keep restarting the game between the attempts to find the ideal sensitivity… Dissapointing that the fix is driving us minority players to find the sweet spot of the sensitivity like this, comparing to the majority who have this scale change to ease setting a precise sensitivity…

        Nonetheless, I want to thank you for responding quickly aswell as releasing fixes such as this for the community free of charge. The work is appreciated! The sensitivity issue is just a minor setback afterall as these fixes include a ton of other great features.


      2. The config file made no difference… I guess I’ll just play without the fix then, unless I somehow find a way to edit the .dll and remove the sensitivity change for my personal use…


    1. Hi there and thank you for the feedback. I have not heard about the issue you are describing before. If you would provide a savegame for one of the affected sections, I could try to reproduce the problem on my end.


    1. Thank you for the save file. Unfortunately my internet connection is down for the next few days and I have to cope with a mobile setup right now. I will look into the issue as soon as I can and come back to you.


  2. Your fix worked great for the last game, but for this one it just crashes my game as it opens. If I remove your file, the game starts normally, but it still has mouse issues.


  3. i enjoy your work but its still annoying when sens increases in zero g or hanging upside down etc, im hoping for a fix for that as well if the reason for this is not too hardcoded.


    1. I am aware that this is an issue and I would like to put some additional work into the mod to fix it. However, developing these kind of mods takes a lot time and I am currently kind of busy with other things. I will probably get back to it at some point, I just cannot say right now when.


      1. Well, I hope you do, cuz i won’t be able to play ds2 without your help. Thanks for your work on dead space 1
