Field of view (FOV)

Fix camera FOV permanently with a key binding[23]
  1. Go to the configuration file(s) location.
  2. Open BIOInput.ini.
  3. Find the [BIOC_Base.BioPlayerInput] section, and add the following period binding to it.
  4. Bindings=(Name="Period",Command="set BioCameraBehaviorFollow CAMERA_FOV 100 | set BioCameraBehaviorZoom CAMERA_FOV 40")
  5. Get to a stage when Shepard can run around, and hit the . (period) key. This needs to be done only once per session.


This fix sets the FOV to 100 and does not mess up conversations or cutscenes. Other values can be tried (default is 75).
Use ThirteenAG's Mass Effect Trilogy FOV Fix
  1. Download the archive from here.
  2. Download and extract the archive to the game directory, where the exe is located (Binaries or Binaries\Win32)


Also works with Mass Effect 2 and Mass Effect 3
Automatically corrects in-game FOV (Hor+)
16:9 only[citation needed]

Borderless fullscreen windowed

Force borderless windowed mode[citation needed]
  1. Set the game to run in windowed mode in the in-game video settings, make sure it's set to the same resolution as your desktop.
  2. Close the game. Make sure you haven't set the game to run in compatibility mode for XP nor Vista, the former causes borderless to be glitchy and the latter leads to a crash. Compatibility mode for 7 (if you're running 8+) is fine, should you need it.
  3. Install Borderless Gaming.
  4. Go to <path-to-game>\BioGame\Splash.
  5. Delete or rename Splash.bmp, this prevents Borderless Gaming from making the splash window borderless, as this causes a crash for unknown reasons. Be aware that the MEUITM mod adds a new splash image, so be sure to re-delete/rename it again should you choose to install/reinstall it.
  6. Run the game and wait for it to get to the main menu.
  7. Run Borderless Gaming, click Mass Effect on the left panel, click the arrow pointing to the right.
  8. In a few moments the game window should become borderless fullscreen. If Borderless Gaming isn't making the game borderless try running Borderless Gaming as administrator.[24]
If UI elements are clipping off-screen, in Bordlerless Gaming, right-click Mass Effect under Favorites, and check No Size Change.

Anisotropic filtering (AF)

High quality AF[25]
  1. Go to the configuration file(s) location.
  2. Open BIOEngine.ini.
  3. Go to [SystemSettings] section and edit the following values like below
High quality AF is automatically enabled by ALOT.

High frame rate

Change frame rate smoothing[20]
  1. Go to the configuration file(s) location.
  2. Open BIOEngine.ini.
  3. Search and change bSmoothFrameRate to FALSE or raise MaxSmoothedFrameRate value.
  4. Save file.
For more information, see the Unreal Engine 3 page.
High FPS affects vehicles physics (including constant bounciness and a wobbling suspension sound).

Depth of field

Disable DOF
  1. Go to the configuration file(s) location.
  2. Open BIOEngine.ini.
  3. Search and change DepthOfField to FALSE.

High dynamic range display (HDR)

Use Special K after D3D11 upgrade[26]
  1. Set the game to run in windowed mode.
  2. Install dgVoodoo 2 in <path-to-game>\Binaries.
  3. Use its configuration utility to force Appearance to Windowed, the highest available Direct3D 11 feature level API, and the DirectX Videocard VRAM the closest to your GPU.
  4. Download Special K.
  5. Install it locally into the aforementioned game folder with SpecialK32.dll renamed to dinput8.dll.
  6. Start the game, and from the SpecialK UI (Ctrl+ Shift+← Backspace) make sure Active Render API is D3D9→11.
  7. From the Compatibility Settings, disable support for the D3D9 render backend
  • if nothing shows up set d3d9 and d3d9ex to false in the newly created dinput8.ini and launch the game again
  1. Set an Override Resolution by clicking once over Window Resolution
  • if targetting fullscreen, make sure to first enable Borderless and Fullscreen Borderless under Window Management
  1. Follow the remainder of the Special K HDR guide.


Resolution cannot be adjusted anymore in-game, but only with StartupResolution and OverrideRes in the .ini files.

  1. Download ME1 Controller Support mod
  2. Extract Config content to the configuration files location
  3. Extract Mass Effect content to <path-to-game>.


Installing this MOD will break some elements of the keyboard and mouse support. The console will work fine. If you want to play with keyboard and mouse, uninstall this mod.
The ini substitutes are read-only to prevent the game from overwriting them. Unset this when adjusting options.
To change sensitivity go to the configuration files location, open BIOInput.ini and adjust following values.

Independent UI and dubbing/captioning

English should be always present, and benefits of a slightly more privileged position[Note 3]. For simplicity the following fixes just assume 2-way mixes with it.
Combining 3 languages (or 2 non-English ones) shouldn't be particularly harder, but when switching to a new localization in Steam/Origin the client will try to prune the previous one files.
Separate the UI from the rest[38]
  1. Install the game in the desired localized language.
  2. Go to the configuration file(s) location.
  3. Open BIOEngine.ini.
  4. In section section [Engine.Engine], set Language=YYY.
  5. Browse back one directory and go to Published\CookedPC\Packages\Dialog (create the missing folders)
  6. Open a command prompt and run the following command (replace <path-to-game>, XXX and YYY where appropriate):
  • mklink GlobalTlk_YYY.upk "<path-to-game>\BioGame\CookedPC\Packages\Localised\YYY\Dialog\GlobalTlk_XXX.upk"


XXX is the language code for the UI, and generally other non-dialog strings.[39]
YYY is the language code for "everything but the UI" (or just the subtitles if also coupled with the other fix).
Separate dubbing from captioning[40]
  1. Install the game in the desired localized language.
  2. Go to <path-to-game>\BioGame\CookedPC.
  3. Open/replace/tinker/trim loading priorities inside FileIndex.txt to change the voices language


Only English FileIndex.txt is ready-made (make sure the Localised GlobalTlk entry points to the one wished for the UI)
Alternatively files can be renamed and moved by hand as shown here.

Issues unresolved

Some menu screens have sides "cut off" on 4:3 screen resolutions

Playing in 4:3 or 5:4 resolutions like 1280x1024 or 1600x1200 (common on moderately high-resolution, non-widescreen monitors and projectors) results in some menu screens displaying incorrectly: the left and right-hand sides of the screen are clipped (as if "zoomed in" too far), so important information cannot be seen (like journal details and the map legend). Screens affected include: Map, Party Selection, Planet details, and Journal. The only workaround is run the game in resolution with wider aspect ratio, i.e. 1920x1080 or 1280x800.

Black screen after loading a save

Black screen after loading a save[citation needed]

If the whole screen is black except for the UI, then Shepard fell through the Normandy and the save is bugged. Only happens on the Normandy, in the Engineering part of the ship. Never save there.

Use console command[citation needed]

Activate the console (instructions on how to enable the console further down) and type At BIOA_NOR00 Start_BIOA_NOR00_01 and press Enter. This will place you at the entrance to the Normandy and you will be able to save and load your game with no problems. If you fall through anywhere else in the game, pctweaks has a comprehensive list of all the "At string newArea" commands.

Issues fixed

TweakGuides has created a comprehensive guide for fixing issues in this game[20]

Game does not start

Install PhysX Legacy System Software[41]
Origin version may also depend on the next fix to run at all[42]

Game always asks for admin permissions (Windows 8.1 +)

This is also responsible for Steam Controller and Steam overlay not working.
Workaround broken Application Compatibility Engine and shim[43][44]
  1. Open the <path-to-game>\Binaries\MassEffect.exe properties
  2. Make sure there are no compatibility/administrator modes set (also remember the "settings for all the users" button)
  3. Open regedit
  4. Navigate to HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers
  5. Create a new string value named <path-to-game>\Binaries\MassEffect.exe
  6. Set its content to RUNASINVOKER


Make sure there are no Compatibility modes enabled for <path-to-game>\Binaries\MassEffect.exe.
It's also highly recommended to remove leftover registry values to avoid issues in other games.[45]

Game still crashes immediately even after having installed PhysX

Disable Mandatory ASLR for the game[46]
  1. Open Windows Defender
  2. In App & browser control, open Exploit protection settings
  3. In Program settings, add an exception for <path-to-game>\Binaries\MassEffect.exe.
  4. Disable "Force randomization for images (Mandatory ASLR)"

Crash after splash screen or black screen

Use updated OpenAL[47][48]
  1. Install latest OpenAL
  2. Delete or rename OpenAL32.dll and wrap_oal.dll from <path-to-game>\Binaries
Disable or update Riva Tuner Statistics Server

Crashes after title screen

Check the last log in %USERPROFILE%\Documents\Bioware\Mass Effect\Logs\ for "Error opening file" clues[49]
Other "failed to load" lines (even those specifying "Can't find file") aren't necessarily indicative of anything special.
If reinstallation still cannot address the error, verify any affected file to have all the required read permissions for the Users or Everyone ACL groups.

Launcher crashes (retail)

Install latest patch[50]

Crash after some few minutes of play

Close any 3rd party application that may hook the game (e.g. AMD Gaming Evolved)[51]

Failed to compile shader ** error

Retail: reinstall game[citation needed]
Steam: check local game cache[citation needed]
Origin: repair game[citation needed]

Characters become black blobs on AMD >K10 CPUs

Use fixed D3DX dll[52]
  1. Download SilentPatchME
  2. Extract d3dx9_31.dll in <path-to-game>\Binaries\
Disable some Processor Specific Graphics Pipeline optimizations
  1. Open regedit
  2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Direct3D\
  3. Create a new DWORD named DisableD3DXPSGP and set it to 1
Use Black Blobs fix for AMD CPU users


This is the only fix working for Bulldozer and Piledriver CPUs, although it removes some lights to solve the issue

Therum missing textures

If when you get to Therum most of the ground is black, then you've got a common texture problem. Some of the black area is safe to drive on but some of it will kill you outright, making it quite hard to navigate.
Therum Missing Textures[53][citation needed]
  1. To restore the texture, go to %USERPROFILE%\Documents\BioWare\Mass Effect\Published\CookedPC.
  2. Delete LocalShaderCache-PC-D3D-SM3.upk.
  3. Go to <path-to-game>\BioGame\CookedPC.
  4. Delete or rename LocalShaderCache-PC-D3D-SM3.upk.
  5. Restart and Therum should look fine.


The game will take longer to boot on the first run after performing the above steps. This is due to the engine recaching all of the textures. Following the first boot, each subsequent boot up should be as normal.
This issue is only found on Therum, so if the above steps do not solve the problem, you can continue to play as normal.

Humongous lens flares cover the whole screen (Nvidia GPUs)

Disable any kind of forced sampling-based anti-aliasing[54]
Can be specifically solved just with better compatibility bits in Nvidia Inspector, but minor lighting irregularities still remain[Note 4]

Bugged lighting all around the map (AMD GPUs)

Make sure application anti-aliasing in the GPU control panel isn't set to "Override Application Settings"[55]

No option for higher resolutions

No high resolution option

The resolution listbox in graphics options does have up/down arrows on the right side, which are easily overlooked, that allow you to choose higher resolutions like 1920x1080.

All textures look incredibly washed out

Also known as "Garrus face fix"
See Force highest quality textures
Make sure Texture Filtering Quality in your GPU control panel is set to High

Saves or settings don't actually get saved

Add an exception for <path-to-game>\Binaries\MassEffect.exe in the used antivirus[56]
If Controlled folder access is enabled, add the game to the allowed apps list[57]
Check the last log in %USERPROFILE%\Documents\Bioware\Mass Effect\Logs\ for issues in the saves folder[58]

No audio at all (menu or ingame)

Disable hardware audio
  1. Un-check "Use Hardware" in in-game "Sound" settings
  2. Open %USERPROFILE%\Documents\BioWare\Mass Effect\Config\BioEngine.ini.
  3. Add or replace the following lines under the [ISACTAudio.ISACTAudioDevice] section:
DeviceName=Generic Software

Dialogue and other audio cutting out

Increase # of sound sources & update rate
  1. Open %USERPROFILE%\Documents\BioWare\Mass Effect\Config\BioEngine.ini.
  2. Add or replace the following lines under the [ISACTAudio.ISACTAudioDevice] section:
