DLC and expansion packs

For some time now Origin will overwrite any installation of the game,[1] including Steam, with a stand alone client independent version of the game with all bought DLCs. Authorization for the DLCs still is dependent of ingame login but it'll work without Origin or Steam.
All of the DLCs are available in a bundle on Origin, bypassing the Bioware Points. Steam and retail versions can use separate installers to access them for free (direct links are provided below for convenience).

Widescreen resolution[edit]

Use Flawless Widescreen
Allows changing FOV
Doesn't work with Origin version properly[9]
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)


Automatically corrects in-game FOV (Hor+)
Works with Origin version.
Works with Mass Effect 1 and Mass Effect 3
16:9 only[citation needed]

Field of view (FOV)[edit]

This method involves Coalesced.ini file. Make sure you have understood what this means.
Modify field of view[10][citation needed]
  1. Go to the configuration file(s) location.
  2. Backup then open Coalesced.ini.
  3. Add the following line under the [SFXGame.SFXGameModeDefault] section:
    Bindings=( Name="Period", Command="set SFXGame.SFXCameraMode FOV 100" )
  4. Edit the key name and FOV value to your liking.
  5. Save changes


Can be used in conjunction with Flawless Widescreen providing that "FOV Limiting" is disabled.

Vertical sync (Vsync)[edit]

Disable Vsync[citation needed]
  1. Go to the configuration file(s) location.
  2. Open GamerSettings.ini.
  3. Add UseVsync=False line under the [SystemSettings] section
  4. Save changes

Mouse acceleration[edit]

Disable Mouse acceleration[11]
  1. Go to the configuration file(s) location.
  2. Open GamerSettings.ini.
  3. Add the following lines:
  4. Save changes
This may not work with the Origin or Steam versions. If this is the case, make these changes in Coalesced.ini (see Editing Coalesced.ini).

Mouse sensitivity[edit]

Fix uneven and/or excessive mouse sensitivity
  1. Disable the Origin ingame overlay. The overlay (on Origin versions at least) is the cause of uneven mouse input and not mouse acceleration. Disabling fixes this.

If your mouse sensitivity is still too high you will need to modify the variable in Coalesced.ini

  1. Locate your Coalesced.ini inside <path-to-game>\BioGame\Config\PC\Cooked
  2. Make a copy of the file
  3. Open it with a text editor that can handle UNIX-format files (Notepad++ is recommended)
  4. Search for and locate "MouseSensitivity"
  5. Change the value from 1.0 to 0.2 or your preference.
  6. Save


Don't modify anything else in the Coalesced.ini otherwise ME2 will fail to start. If that happens, simply restore the backup copy you made as above and start again.

Controller support[edit]

This mod brings full XInput controller support to the game with haptic feedback support. This mod is currently complete (see official thread).

Use the ME2Controller mod.

For DualShock prompts use PlayStation Icons

Simultaneous Mouse and joystick support for Steam Controller users[edit]

Enable joystick move to be used with mouse[13]
  • Go to file location <path-to-game>\BioGame\Config\PC\Cooked\Coalesced.ini
  • Open up the Coalesced.ini file with notepad or notepad++
  • Under [WinDrv.WindowsClient] change the value for AllowJoystickInput from 0 to 1.
  • Under [SFXGame.SFXGameModeBase] add the following lines
Bindings=(Name="XboxTypeS_LeftX",Command="Axis aStrafe Speed=1.0 DeadZone=0.3")
Bindings=(Name="XboxTypeS_LeftY",Command="Axis aBaseY Speed=1.0 DeadZone=0.3")

Crash during vehicle chase on Illium[edit]

At the end of the taxi chase with Liara on Illium, during the cutscene, the game freezes completely showing either a frozen image or a black screen while the music continues.
Use config tool to change from fullscreen mode to windowed borderless
Run in Windows 7 compatibility mode
Add the command line argument -nomoviestartup to the shortcut you use to play (use \Binaries\MassEffect2.exe)
Uninstall and re-install all game files and DLCs (or use Origin's Repair feature)

Issue may still persists after all of these have been done

No sound in Windows 10[edit]

For some reason the audio will stop when you run the game.
Run the game in windowed mode or borderless window

Issues fixed[edit]

Installation interrupted[edit]

Install the game from a shared drive from another computer[citation needed]
  1. Insert Disc 1 and share it through Windows.
  2. When the installer asks for the second drive, stop sharing the first disc, replace it with the second and start sharing it.
Fix the corrupted folder path in Windows registry[17]
  1. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\BioWare\Mass Effect 2\
  2. Find the Path variable on the right and double click it to open for editing.
  3. Add a backslash (\) to the end of the path string and hit OK.
  4. The game should now launch from Origin.

Physx Error on Startup[edit]

Install Nvidia Physx System Software

Cerberus Network autologin failure[edit]

Enable .NET Framework 3.5.1[citation needed]
  1. Go to Windows's Control Panel.
  2. Go to Programs -> Turn Windows features on or off.
  3. In the tree stucture, check both boxes under Microsoft .NET Framework 3.5.1.
  4. Restart your system.

Black screen when entering/exiting planets[edit]

Black screen entering/exiting[citation needed]
If you get a black screen when entering/exiting a planet, specifically the shadow broker base, this is fixed by starting the game with the -nomoviestartup command. To do this:
  1. Go to the MassEffect2.exe file. It's in the .../Mass Effect2/Binaries folder.
  2. Create a shortcut to the MassEffect2.exe file. Right click the shortcut, and click 'Properties'.
  3. Add -nomoviestartup to the 'target' field. It should look like this: "...\Mass Effect 2\Binaries\MassEffect2.exe" -nomoviestartup
This shortcut (skip the actual launcher) will not freeze when entering/exiting planets
Important Unfortunately, when using this command, your game WILL freeze when trying to enter the citadel. The only way to circumvent this is by saving the game, exiting and restarting it with the regular MassEffect2.exe
On the Origin version of the game, the name of the file you need to create the shortcut for is "ME2Game.exe", so the shortcut should look like this: "...\Origin Games\Mass Effect 2\Binaries\ME2Game.exe" -nomoviestartup.

Dark lighting in cutscenes[edit]

Adjust filmic response shader[18]
  1. Open <path-to-game>\Engine\Shaders\UberPostProcessBlendPixelShader.usf with a text editor.
  2. Find float3 x = max(0,InLinearColour-0.004); on line 45
  3. Replace with float3 x = max(0,InLinearColour);
Alternatively, rather than deleted, the darkening factor could be tweaked to other ⩽0.001 values[19][20]

Clipping into walls/objects[edit]

This method involves Coalesced.ini file. Make sure you have understood what this means.
Add the option to noclip out of the object[citation needed]
  1. Under [SFXGame.SFXGameModeDefault] add:
Bindings=( Name="Add", Command="Ghost | OnRelease Walk")


Holding the NUMPAD + key in-game will now make you noclip until you release the button.


OR, if you have console enabled, hit tab and type "ghost" then hit enter. Then when you're out of the wall or through the spot you needed to get through, do the same and type walk. Then you don't have to leave the game.

Game freeze on Illium[edit]

Walking through the ground level corridor, that connects to the other side of the map, under Liara's office may cause a black screen and CTD.
Enable windowed or windowed borderless mode[citation needed]
  1. Open Mass Effect 2 Config > Video
  2. Windowed > Windowed
  3. Window Mode > Borderless
  4. In the menubar select Mass Effect 2 > Save Settings
After passing through the corridor, it's safe to enable fullscreen mode again.
Walk slowly instead of running[citation needed]
In some cases simply walking through the hallway avoids freezing. With this method you can leave fullscreen on.
Disable light environment shadows[citation needed]
If borderless mode didn't fix this issue try to disable light environment shadows it can also fix this problem tested with borderless mode its also fixed random crashes in Shadow Broker and Arrival DLC

Crash when entering the galaxy map[edit]

Re-enable audio[21]
  1. Open %USERPROFILE%\Documents\BioWare\Mass Effect 2\BIOGame\Config\GamerSettings.ini
  2. Delete the DisableAudio line.
  3. Save the file.

Unable to save any more games[edit]

Patch game files[22]
  1. Download Mass Effect 2 PCC Patcher (mirror)
  2. Extract the program in <path-to-game>\Binaries\ and open it
  3. Provide the path for the following packages and load them
    Engine.pcc: <path-to-game>\BioGame\CookedPC\Engine.pcc
    SFXGame.pcc: <path-to-game>\BioGame\CookedPC\SFXGame.pcc
  4. Go to Gameplay tab and tick Increase max saves count
  5. Save packages

Long loading times with patch 1.02[edit]

Use Playwrite's MassAffinity program[citation needed]
  1. Download MassAffinity.
  2. If automatic Mass Effect 2 directory detection fails, manually select it.
  3. Click the "Run Game" button.


Use the included batch file if you need to set up again the tool

Conrad Verner claims player has pointed gun at him[edit]

To prevent this bug use ME1 Recalibrated in Mass Effect and ME2 Recalibrated
Fix save file variable[23][24]
  1. Download ME2 Gibbed modified Save Editor (mirror).
  2. Run it and open your actual savegame.
  3. Go to Plot tab and then to ME1 Imported plot table.
  4. Go to Flags sub-tab and untick [Conrad] (3) Intimidated Conrad (Renegade).
  5. Save changes


This only works if the player has not spoken with the asari bar owner in Illium yet.

"Unable to authorize the listed DLC" error[edit]

"Unable to authorize the listed DLC" error[citation needed]
  1. Use Binkw32 proxy DLL.
  2. Block internet connection of ME2game.exe through your firewall settings.


Optionally you can disable automatic login through in-game settings although any time the game does attempt to connect it'll reverse the DLC crack.
If after installing the new binkw32.dll, the game fails to start, giving an error like "binkw32.dll is either not designed to run on Windows or it contains an error", try the gcc compiled version instead:

Importing ME1 character still launches the interactive story[edit]

This happens if you have installed the Genesis DLC (You can un-check it during download on Origin)
Can invalidate your ME1 character's decisions in place of new ones
Remove the DLC[25]
  1. Go to <path-to-game>\BioGame\DLC\
  2. Remove the DLC_DHME1 folder

Forcing Anti-Aliasing causes heavy geometry flicker and other artifacts[edit]

This can potentially happen if you force AA from control panel
injectSMAA[citation needed]
  1. Disable any forced AA you had before
  2. Download injectSMAA
  3. Copy the contents of d3d9 folder to <path-to-game>\Binaries\

When moving the camera with the mouse the game starts stuttering/having performance problems[edit]

This is likely an issue with the mouse polling rate on systems with Windows 10 installed
Lower mouse polling rate to 500Hz or lower[citation needed]

Editing Coalesced.ini[edit]

Some of the fixes for this game require you to modify this special file, but editing it in the normal way will cause the game to crash.
Editing Coalesced.ini[citation needed]
  1. Locate your Coalesced.ini inside <path-to-game>\BioGame\Config\PC\Cooked
  2. Open it with a text editor that can handle UNIX-format files (Notepad++ is recommended)
  3. Make the changes you have to and save
  4. Download ME2IniFixer (mirror) and extract it in the folder your Coalesced.ini file is
  5. Run it from there.


Do not use default Windows Notepad or Word. They will permanently corrupt your ini file. (WORKS with notepad!)
  • Advanced users could also use Mass Effect 2 Coalesced Editor (mirror) which is recommended
  • It might be necessary to make the Coalesced.ini file read-only (right-click -> Properties -> Attributes: Read-only) as the game can restore your edits. If you want to change anything in it, simply uncheck the Read-only box.

Increase shadow resolution[edit]

Increase shadow resolution[citation needed]
  1. Go to the configuration file(s) location.

  1. Go to the configuration file(s) location.
  2. Open GamerSettings.ini.
  3. Under [SystemSettings] add one or more of the following lines:
  4. Save changes
