DirectX 11 in WOW

Hmm, why exactly does WOW have DX11? Well let’s see what it adds. According to PCGH, the World of Warcraft: Cataclysm beta support Dx11 via a shortcut command or config edit. Right now, DX11 is used to create water reflections for various objects, so keep your eye on the water in the screens. However, there seems to be a downgrade when it comes to water transitions, which PCGH thinks might be a bug.

To do this, expand a shortcut to the woW.exe with “-d3d11”. Alternatively, open the “Config.wtf” in “\ World of Warcraft \ Beta \ WTF” and add the line SET gxApi “d3d11” (with quotes). With the experimental DirectX 11 path the visuals changes: Spells now reflect in the water or lava, so do the characters and the sky. However the pretty transitions between water and shore disappear – hopefully, this is just a bug.

I am not exactly sure why they need to use Direct X 11 to implement these effects, perhaps it’s due to less overhead in crowded areas?
