TL;DR 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. Quick start guide: Extract the file dinput8.dll to your main game folder. For example: "C:\Program Files (x86)\Origin\games\Dead Space 2\". Start the game like you would normally, for example directly through Origin or Steam Features 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. Its features include: 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 Instructions Supported Versions This mod is designed for the latest, fully patched versions of Dead Space 2 and might not work when used with older or otherwise modified executables. Origin/Retail Steam Install The mod does not make any permanent changes to the game or to Windows and can easily be removed. Extract the file dinput8.dll to your main game folder. For example: "C:\Program Files (x86)\Origin\games\Dead Space 2\". Start the game like you would normally, for example directly through Origin or Steam Uninstall Remove or rename the dinput8.dll from the folder of the game. Known Issues There are some short sections in the game where the fix does not work properly, for example the zero-g areas. I am currently looking for savegames close to those locations, so I can investigate the issues. The fix is also currently not compatible with latest version of ReShade, due to raw input conflicts, which result in the fix not receiving any mouse data. Additional Information Antivirus Software Since this mod consists of an executable DLL file that uses "hacking techniques" such as injection and hooking, it could be classified as malicious by antivirus software. In that case, it might be necessary to add an exception rule to the scanner. If you lack the trust in random people on the internet -- and I would not blame you -- feel free to use a meta online virus scanner like VirusTotal to verify the file. Loading Other Fixes/Mods/Injectors To increase the compatibility with other mods or injectors that are using a wrapper DLL, this fix offers two methods for remote loading of additional files. Note that there might still be compatibility issues between the different fixes, mods or injectors that have nothing to do with the loading process. File method: The mod will load another dinput8.dll automatically if it has the name dinput8_Remote.dll. Just rename the DLL you want to load accordingly. Using this method will lead to an error if the renamed DLL is not itself a dinput8.dll. Folder method: The mod will also automatically load all DLLs regardless of their names in a dinput8_Remote sub-directory. Just create a corresponding folder in the install directory of the mod. This is the only way to load multiple (conflicting) files. Acknowledgments I would like to thank Kaibz for his detailed bug reports and testing for the v1.0 version of the 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. Overview Description 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. Features 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. Instructions 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. Install Note: The fix does not make any permanent changes to the game or the system and can easily be removed (see below). Extract the file dinput8.dll to your main game folder*. For example: "C:\Program Files (x86)\Steam\steamapps\common\Dead Space" 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. Uninstall 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. Acknowledgments I would like to thank Magmarock (Steam/gog) for his detailed bug reports and testing for the v1.0 version of the fix.
