Essential improvements[edit]


Official patch[edit] Not needed for the release.

Multiverse Edition[edit]

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[edit]

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.
091225 by Drog Black Tooth. Highly recommended bug fixes.

High Resolution Patch[edit]

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.
1.5 by Drog Black Tooth. Allows any user-set resolution, UI tweaks, larger fonts.

Issues fixed[edit]

Files not installed properly[edit]

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[edit]

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[edit]

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[edit]

  1. Go to the installation folder
  2. Open SierraLauncher.ini
  3. Find Game1Cmd= and replace line with Game1Cmd= -no3d -doublebuffer -scrolldist:0 -scrollfps:70
