Essential improvements


Official patch Not needed for the release.

Multiverse Edition

Complete overhaul with all the patches listed in this article, as well as others, bundled together in one installer that offers a lot of options.
For a widescreen monitor, it is recommended to use a 1366x768 resolution. Higher values can make the UI and dialogue difficult to see.
Arcanum Multiverse Edition [ENG] by the Multiverse Team.

Unofficial patch

Windows 11 users should only use the latest Unofficial patch.
Highly improved townmaps and soundtracks (from the vanilla 128kbit/sec to 320 kbit/sec) can be found alongside this patch.
Not compatible with older savegames.
Latest version of the patch has been known to be unstable on Windows 10 and below.[1] Use the 091225 installer instead if you are having problems with the latest unofficial patch.
200611 (2.0.2) by Drog Black Tooth. Highly recommended bug fixes.

High Resolution Patch

If you are unable to pan the camera past the edge of the screen with the high resolution patch enabled, add -scrolldist:0 -scrollfps:70 to the target line in the shortcut of the game.
The High Resolution Patch is already included in the Unofficial Arcanum Patch. For a separate installer check out 1.5 by Drog Black Tooth. Allows any user-set resolution, UI tweaks, larger fonts.

Issues fixed

Files not installed properly

Recommended to avoid default installation folder, as this can lead to issues where certain files are not properly installed.
Run installed as administrator[citation needed]

When running the installer, be sure to right-click on the .exe, and select "Run as Administrator".

Loading screen freezing

Freezing known to happen on systems with multi-core CPUs.[citation needed]
Set CPU affinity[citation needed]

Setting CPU affinity should solve this problem. Create a shortcut, and in the shortcut's "Target" field, insert %WINDIR%\System32\cmd.exe /C start "ARCANUM" /D "C:\ARCANUM" /high /affinity 1 "C:\ARCANUM\arcanum.exe" Be sure to replace C:\ARCANUM with your actual Arcanum installation folder. If needed, you can add additional command-line parameters to the end.

Graphical issues

Set target field[citation needed]

Adding -no3d -doublebuffer to the end of your Arcanum shortcut's "Target" field.

Delete or rename ddraw.dll[citation needed]

Delete or rename ddraw.dll.

Performance issues

  1. Go to the installation folder
  2. Open SierraLauncher.ini

  2. Open the archive and extract the content of the folder to <path-to-game>/Arcanum
  3. If prompted, click yes to replace ddraw.dll
