Dead Space Mouse Fix

What is this?

This fix makes Dead Space 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.



The mouse controls in Dead Space are notorious. While many players report issues with positive or negative mouse acceleration or overall sluggish movement, others state that the controls are not that bad. This is because the engine applies a lot of transformations to the input that are based on frame time. This leads to movement that is generally better when the frame rate ist stable. The problem gets worse when activating V-Sync. This is why popular workarounds recommend to disable V-Sync and cap the frame rate to avoid fluctuations.

Unfortunately, this also means that playing at higher frame rates is often not feasible, which also prevents users from taking advantage of GSync, FreeSync, Fast Sync or similar technologies.

This fix attempts to circumvent those problems by acquiring raw mouse input and injecting it directly into the game’s camera functions, making the controls as independent of the frame rate as possible.

While the movement is still not as perfect as in other games — e.g. DOOM — it should be a huge improvement to the default behavior.


  • 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

Note: Although the input is pretty raw when aiming, it may still feel a little bit sluggish when moving and turning the camera at the same time. This is because the game applies calculations based on the momentum of the player character to the input.


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.

  • Steam
  • GOG
  • Origin*

*The Origin version might crash on start when the ingame overlay is enabled. If that happens, disable the overlay in the game properties in Origin. If the game still crashes the problem might be unrelated to the fix as this is an ongoing issue with the Origin version. In that case uninstall the fix and try to resolve the issue first before installing the fix again.


Note: 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)\Steam\steamapps\common\Dead Space"
  2. Start the game like you would normally, for example directly through Steam, Origin or GOG Galaxy

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: 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 don’t — 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

There are currently no known issues with the fix.


I would like to thank Magmarock (Steam/gog) for his detailed bug reports and testing for the v1.0 version of the fix.

  1. Many pros say you’ve to become more centered on producing the correct represents
    while in the stand versus how quick or how rapidly your bankroll
    keeps growing.


    1. Hi there. I am aware of the issue, but because I am on the road right now I unfortunately cannot provide an alternative until I get home tomorrow evening. I will see what I can do to get the problem fixed on PC Gaming Wikis end.


  2. This is really a service to the community that should be honored more. These games are basically unplayable and a pain in the ass on today’s standards and hardware. You sir, deserve a medal! And yeah, fixing the download would be appreciated as I wanted to play DS and tried to fix this game all day. Could you maybe upload a mirror to ? We have been up for 3 years now and would love to help anyone out! No redirections, no ads, no strings attached, direct download. Cheers!


  3. Amazing work, the game feels way better with this fix! I’m wondering about this part “This is because the game applies calculations based on the momentum of the player character to the input.” The camera movement is deinitely worse when moving, and I was wondering if it’s possible to override those game calculations somehow to achieve similar camera movement to the stationary one?


    1. Yes, in principle this is possible. However, it is not easy to do because there are a lot of things that are intertwined with the character movement and just replacing it might also break other things. Additionally right now I don’t have the time to continue working on the mod anyway :/


      1. Thank you for the answer, I appreciate all the work you already put into this mod and I understand that it is a low priority project. Maybe someday in the future this change will happen, for now I’ll try to play with the controls as they are :)


  4. I finished the game using this fix and it was mostly a very good experience, definitely better than the default controls. Aside from the movement issue mentioned before I also noticed that the sensivity goes way high when walking on organic floor(the walking animation changes, I expect this to be related). This occurs on numerous occasions, but the first time is in Chapter 3 if I recall correctly. If the creator or anyone else(I haven’t seen the source anywhere though) will be working on this mod again in the future, it’s something to keep in mind :)


  5. Hey Methanhydrat… I’m just now replaying this game and using your .dll file. In the game, I went ahead and maxed the mouse sensitivity and all is well. I’ve run into a little issue using the tweak. There are areas in the game where the floor has this organic gross stuff. When you walk in it the game will slow your movement and you can’t run. That is all normal and intended. When you move your mouse while in this stuff the camera goes wild. It is like the sensitivity doubles. When you walk back onto normal flooring then the mouse is good again. I was able to fix it by removing your.dll but then, of course, you have the crap mouse movement all the time. Thank you for these fixes.


    1. Hi there and thank you for the feedback. This is a known problem and unfortunately I got never around to fix it. But as far as I know there are not that many places in the game where it occurs. I will still keep it in mind for a potential future update.


  6. The problem with increasing the sensitivity of the mouse in rooms with floors covered with organic matter were introduced in version 1.0. Version 0.5.1 did not have it.


  7. YESSS, dude! Your fix is working on Linux Wine with the GOG version!

    Just put d8input.dll into the game directory AND add dinput8 in the library overrides in winecfg. Then start the Game from within the game directory. You can also verify if it loaded with WINEDEBUG=+loaddll wine “Dead Space.exe”.

    Thank you so much, now I can play the game!


    1. I am glad to know you got it working. I was actually about to tell you that the fix is not compatible with Wine, due to the way they implemented DirectInput. However, after you told me I took a look at the changes on GitHub and they actually fixed that problem 3 months ago. This is good news, because there were people asking for Linux support on some of my other fixes as well, which should (for the most part) also work now.
