Troubleshooting

Mac

See the Intel Mac build's page for Mac-specific issues.

Linux

See Playing in Linux § Troubleshooting for Linux-specific issues.

Windows

Most of the problems in Oni itself can be solved by installing a community patch:

• The Daodan DLL (see that page for manual installation instructions),
• the Anniversary Edition (installs and updates the Daodan DLL automatically), or you could
• use OniX, the new game application for Windows.

But some problems remain unfixed, so the information below may be useful.

Installer

The installer on the CD-ROM, OniSetup.exe, may no longer run as of Windows 10. You can extract the game data from the installer's data file (ONISETUP.002) using Universal Extractor.

Blam!s

Have you seen this message?

There are several reasons why Oni might exit with such a message. The most common cause is solved by the Daodan DLL and OniX, but if neither of those fixes it…

The Blam page contains a thorough list of things that cause Oni to "blam".

Mouse/keyboard problems

See Mouse control issues.

Low-quality texturing/models

Make sure the Quality slider on the Options screen is set to maximum.

Low frame rate

Only happens when certain particles are onscreen

There is no fix for this. Try not to have those particles onscreen =^-^=

Power management issue

This can be a problem on laptops. Under certain conditions the performance of the computer will decrease dramatically, for example:

• if you run on battery power
• if you let the computer overheat

Widescreen and high resolution issues

To get Oni to support widescreen/high resolutions, install the Anniversary Edition or just the Daodan DLL and the resolutions supported by your system should appear on Oni's Options screen.

Things look tiny

The Main Menu in Oni and all splashscreens are 640x480. The in-game HUD (the two circles) are also fixed in size. Since these are never stretched to fit the screen, they will look increasingly small as your resolution gets higher. However this experimental fork of the Daodan DLL does allow the HUD to be scaled. Splashscreens will become 1024x768 if you install the AE mod "HD Screens".

If you are using the Anniversary Edition and the Installer's UI is tiny and cramped, see Anniversary Edition/Installer § GUI scaling for the fix.

Rendering offset from center

When running the game at wide resolutions (e.g. 3440x1440) it may render offset from the center of the screen:

There are three known solutions:

A. Set Windows' display scaling to 100%.

B. Turn on the High DPI scaling override for Oni:

• Right-click on Oni.exe and choose "Properties",
• go to the "Compatibility" tab,
• click the "Change high DPI settings" button,
• check the "Override high DPI scaling behavior" box and set the scaling to "Application", or
• try the Program DPI section above that in the window.

C. Install the Daodan DLL 4.2 Beta:

• Download it from here,
• back up the existing binkw32.dll in your Oni\AE\ folder, and
• place \build\binkw32.dll from the ZIP into your Oni\AE\ folder.
