Note: This CVar is linked to gxDepthBits. If you change this, gxDepthBits should be the same setting.Edit

Sets the amount of Color Bits wow uses. Values range 16, 24, 32.

Default SettingEdit

24

Possible SettingsEdit

16 

16-bit color (High Color)

24 

24-bit color (True Color)

32 

32-bit color (Deep Color)

Changing this settingEdit

This CVar requires a UI reload. In-game, type the following

/console gxDepthBits setting
/console gxColorBits setting
/console gxRestart

Alternatively, you can exit wow, open the Config.wtf file, and add the following line:

SET gxDepthBits setting
SET gxColorBits setting

Notes on 16-bit settingEdit

As of 3.1, 16-bit is no longer a valid setting in the Interface dropdown menu^[1]. However, if you still need to use this setting due to a very low-end graphics card, you can via the in-game macro:

/console gxDepthBits 16
/console gxColorBits 16
/console gxRestart

Be aware that this setting does NOT save when you shut down the game, and you'll have to run these lines every time you log in.

PatchesEdit

Patch 3.1.0 (14-Apr-2009): 16 bit color no longer in the Interface menu - can still manually set it however. 
Patch 1.6.0 (12-Jul-2005): Added
