Diablo III

Diablo III is the third title in the Diablo series (preceded by Diablo in 1996 and Diablo II in 2000). It is developed by Blizzard.

Prelaunch information (expires 15 May 2012):

• Launch Day Preparation Guide.

Windows

Availability

All versions of Diablo III unlock a download of the game on a Battle.net account, which does not require installing an external downloader or client. Retail editions are expected to be cheaper than directly purchasing from Battle.net.

Battle.net

The game is fairly restrictive in requiring constant online access in order to play both single and multiplayer portions of the game, which is a departure from how Diablo II and StarCraft II handled their singleplayer campaigns. An 'always-on' connection requirement for singleplayer can be considered a form of Digital Rights Management (DRM).

Video Settings

Multi-Monitor

Reportedly working by setting Fullscreen Windowed mode and setting a multi-monitor resolution.

Graphics Adjustment

D3Prefs.txt

Some settings are held in the file D3Prefs.txt:

• Windows 7: C:\Users\%Username%\Documents\Diablo III\D3Prefs.txt

Settings can be adjusted, such as:

• TonemapExposure
• TonemapContrast
• TonemapSaturation
• TonemapGain

Darker D3

Using the Darker D3 Pixel Shader by Pyloneer, it is possible to make a change to the brightness and sharpness of the shaders.

Usage

• Run Diablo III at least once.
• Select a setting from the website.
• Extract the .zip into the Diablo III folder.
• Use the 'Pause' key to toggle the effect.

Be aware that modifications to Diablo III files are against the Terms of Use and may result in a ban.

Improve Graphical Sharpness Filtering

The FXAA Injector is reported to work with Diablo III to improve graphical sharpness filtering.

Migrating From Beta To Full Release

Blizzard has advised those who have the beta installed, to uninstall the beta and delete all extra beta files, including:

• Windows XP: C:\Documents and Settings\All Users\Application Data\Battle.net
• Windows Vista/7: C:\ProgramData\Battle.net

Once the files are deleted, run the full retail installer.

"Updating game files" Issue

Some players are reporting the game getting stuck at installation in the "Updating game files" part.

Method - Disable Anti-Virus Software

• Turn off your anti-virus software and firewall.
• Loading the setup file again.
• Running the launcher as administrator.

Method - Connect Using Different Network Adaptor

The Blizzard Agent may be attempting to connect over the wrong network adaptor. The following steps may resolve your issue (in Windows 7):

1. Open the Control Panel.
2. Select "View network status and tasks".
3. Select "Change adapter settings".
4. Right click on each adapter and select "Disable". Leave your primary adapter (the one that provides your internet connection) enabled. You should now have only one enabled adapter.
5. Visit google to ensure you are still connected to the internet.
6. Navigate to "C:\ProgramData" (a hidden folder) and delete the folder named "Battle.net" if it exists.
7. Retry the installer/launcher.

Method - Delete/Modify Agent Files

Delete Agent.exe in:

• Windows 7: C:\ProgramData\Battle.net\Agent\

Modify Agent.db by:

• Opening using notepad.
