CVar gxApi

Switches between 3d engines. Accepts d3d9, d3d11, gll or opengl as parameters.

Default

 * d3d9:DirectX 9.0c Memory management system 2.0 As of patch 4.0.0, d3d9ex is now d3d9. The old d3d9 mode is no longer available and d3d9ex cvar is no longer available.

Possible Settings

 * d3d11:New DirectX 11 experimental engine - only works with Vista (Service Pack 2 and KB971512 required)/Windows 7, alongside DirectX 10/DirectX 11 graphics cards. Enables World of Warcraft to use Shader Model 4 and 5.


 * opengl:Alternative renderer, mainly used for troubleshooting purposes and under Linux/WINE. Not recommended for Windows users except for testing purposes as it can cause WoW to crash itself. Patch 4.0.0 enables hardware cursor in OpenGL mode.

Default

 * GLL:Rewrite of OpenGL, allowing for more graphics card usage, resulting in higher fps.
 * Requirements for GLL:
 * Intel processor
 * MacOS X 10.5.7 or later
 * (Intel GMA 950 is not supported for now)

Possible Settings

 * opengl:Recommended for most users

Changing this setting
To change the setting, exit WoW, open the Config.wtf file, and add the following line: SET gxApi setting

Changing the setting with a graphics engine restart in-game crashes the client.
