Issues unresolved[edit]

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

Playing in 4:3 resolutions like 1600x1200(useful for 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. Currently the only known fix is to use a 16:9 screen resolution when playing, like 1920x1080.

Black screen after loading a save[edit]

Black screen after loading a save

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.

Issues fixed[edit]

TweakGuides has created a comprehensive guide for fixing issues in this game. It can be found here.

Game simply doesn't start[edit]

Run the game as an admin
If you have the Steam version, run it as admin.
Update the game through Origin
This fix is for the Origin versions of the game.
  1. Go to "my games"
  2. Right click on the "Mass Effect" icon
  3. Click the "Check for Update" button"
  4. The latest update will be installed.
Use regedit[5]
  1. Open regedit
  2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\AGEIA Technologies
  3. Edit the enableLocalPhysXCore REG_BINARY (create, if necessary)
  4. Assign this your actual network card MAC address as value


Your MAC address can be found by clicking the "Details" button in the "Status" of your network card (inside the Windows control panel). In case of multiple network cards you'd better try until you find the right one.

Launcher crashes (retail)[edit]

Install latest patch

Failed to compile shader ** error[edit]

Retail: reinstall game
Steam: check local game cache

Therum missing textures[edit]

Therum Missing Textures[6]

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.

  1. To restore the texture, go to %USERPROFILE%\Documents\BioWare\Mass Effect\Published\CookedPC
  2. Delete LocalShaderCache-PC-D3D-SM3.upk.
  3. Restart and Therum should look fine.

If this however wouldn't fix the problem. The issue is not to be found anywhere else than on Therum.

People and objects become black[edit]

Disable lighting[7]

Your squad, enemies, and objects that can be interacted with become boxy black blobs. This is a known problem on newer AMD processors. To fix change the viewmode to unlit.

  1. First you will need to enable the developer console.
  2. Boot up Mass Effect, open the developer console by hitting ~ and type in viewmode unlit. Should be good to go.
It's possible these issues will only affect you in very specific areas, namely an area on Noveria and another on Ilos. After exiting these areas you can use viewmode lit to revert Mass Effect to its normal lighting. There's a possibility you will need to unequip then reequip armor to fix them after doing so.

IGameExplorer --> Verify Access. Unable to verify access to the game[edit]

IGameExplorer --> Verify Access. Unable to verify access to the game.

If you receive this message, it may be fixed by running the .exe in compatibility mode for Windows XP Service Pack 2. Be sure to do this for the actual MassEffect.exe and not the launcher. The final folder tree will be \Mass Effect\Binaries\MassEffect.exe. The preceding folders will of course depend on how you installed the game (via Steam, via Origin etc.).

  1. To set the compatibility mode, right click the .exe, select properties.
  2. Go to the compatibility tab, select an option from the drop down list.

No high resolution option[edit]

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.
