[MassEffectMouseFix] Remove Mouse Acceleration

This fix makes Mass Effect use raw mouse input and removes the game's mouse acceleration. It is easy to install and use and does not require any external configuration.

Overview

Description

While the mouse controls are pretty responsive, the first Mass Effect suffers from mouse acceleration, which can't be turned off via the ingame settings or with the usual approaches for other Unreal Engine 3 games.

This fix removes the acceleration by acquiring raw mouse input and injecting it directly into the game's input function.

Features

• Raw mouse input
  
• No additional smoothing or positive/negative mouse acceleration
  
• Configuration via the ingame settings as usual
  
• Simple installation and usage without any external configuration

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 won't work. This also means that if a game were to be patched -- which is very unlikely at this point -- it would break the fix and require it to be updated.

• Steam
  
• Origin
  
• Retail, v1.02

Note: All available versions of the game can be enabled on Origin one way or another. See this link[pcgamingwiki.com] for details.

Install

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

1. Download this[community.pcgamingwiki.com] zip-file
2. Extract the file dinput8.dll to your main game folder. For example: "C:\Program Files (x86)\Steam\steamapps\common\Mass Effect\Binaries\".
   
3. Start the game like you would normally, for example directly through Steam or Origin

Uninstall

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

Known Issues

There are currently no known issues with the mod.

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.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.

I used the Nexus mod link btw as the pcgamingwiki one doesn't exist anymore.

So, I'm baffled as to how little exposure this page has considering the severity of the mouse acceleration in Mass Effect 1.

This fixes it to how it ought have been. And Bioware, having started in the PC world should have known better than to have that acceleration stuck in the game like that even back in 07.

Thank you for this. Have some treasure.

Hey, finally in 2021

[Methanhydrat]

Thank you for the acknowledgment. I am glad you like it.

I think one of the reasons the Mass Effect fix is not that popular is that for such an old game it is difficult to spread the word around that the problem is fixed. Although by now it got pretty high in the Google search ranking, you still get a lot of information that you can do nothing about it. Additionally, it is also not a major issue. In Dead Space the mouse barely works for some people when not using any fix. Compared to that, the acceleration issue in ME1 is kind of minor. For example, the Steam forums barely contain questions about it.

I agree with you that the guide system of Steam is kind of lackluster. I will probably post the fix on Nexusmods soon. I recently posted my Dark Souls Mouse Fix there and I think Nexus has a better discoverability than a Steam guide and is also easier to maintain.

and steam guide system is not great. I have to scroll all the way to the bottom to find your fix. Found it on pcgamingwiki before and was curious why no one mention this on steam. And still it was hard to find it here. Hope this will get more popular with time. thanks for taking your time to make this

[Penguin]

so strange that your fix is not popular. Especially now when many ppl replay this game before new mass effect. Even your similar fix for dead space got more attention. Maybe mouse problems doesn't bother a lot of people or its just too late for this games. Anyway thanks you for this fixes, will replay dead space after mass effect
