Field of view (FOV)[edit]

Set custom FOV[citation needed]
  1. Go to HKEY_CURRENT_USER\Software\Eidos Montreal\Thief\Graphics\
  2. Open FOVCorrection
  3. Use a hexidecimal value to adjust the FOV, e.g. 9C40 (which is hexadecimal for 40,000) will add 40° to the 90° base FOV.
  4. The change will remain as long as the in-game FOV slider is not touched.

Fixing "Timed Fade" option for in-game HUD[edit]

Fixing "Timed Fade" option for in-game HUD[citation needed]

When Health, Focus, Ammo and Inventory are set to "Timed Fade" in the Game & HUD menu, they only fade to around 50% opacity. This fix will make them completely disappear after a short while of inactivity, relieving the HUD of clutter.

  1. Open <path-to-game>\ThiefGame\Config\ThiefUI.ini
  2. Find mInvSelectionAlphaMin=, mHealthAlphaMin= and mFocusAlphaMin= and change their values to 0.0f;
  3. Save your changes.


No in-game settings override these, so no need to set the file as read-only.

Disable mouse smoothing[edit]

.ini edit[citation needed]
  1. Go to game config folder <path-to-game>\ThiefGame\Config\
  2. Locate file ThiefInput.ini and open it in text editor (notepad for example).
  3. Locate bEnableMouseSmoothing and change its value to false.

Reduce mouse input lag[edit]

Reducing mouse input lag[citation needed]

If the "Exclusive Fullscreen" setting is unchecked, the visuals will be one frame behind your input. You can fix this by either checking "Exclusive Fullscreen" in the game options, or by disabling "one frame thread lag" in the configuration files like so:

  1. Open <path-to-game>\Engine\Config\BaseEngine.ini
  2. Change OneFrameThreadLag=True to OneFrameThreadLag=False
  3. Save your changes.

If this doesn't help, see "High frame rate" above.

Issues fixed[edit]

Missing Voices, Subtitles, Music, and Some Sound Effects[edit]

Install game on internal drive[6]

If the game is on an external drive, voices, subtitles, music, and some sound effects like lightning may not play during the game. This can easily be observed in the prologue cutscene, where Garrett should be speaking. If you installed the game on an external drive, try moving it to an internal drive (it does not have to be the C drive).
