The Gaming Report – DirectX 11 in WoW

There are a lot of ellaborate guides on the web on how to enable experimental DirectX 11 rendering in the recently expanded huge MMORPG World of Warcraft Cataclysm.

So first: what will this do for you? Well if you have a decently new videocard, switching to DirectX 11 will possibly bring increasing Frames Per Second in most zones on the highest of details.

While DirectX 9 may be a bit slower, you won’t feel at a visual disadvantage to those using the newer version just because you don’t have a compatible card or using Windows 7 while you are just under good ol’ XP (DirectX 11 is not available for this OS). Every effect still looks the same. The only gains are in performance.

Also, you will probably notice some glitches along the way on some systems – depending on your hardware configuration. Despite that however, there’s no loss in trying to see how it runs on your system. Personally I found some problems with water rendering on NVIDIA cards or just water borders while they transition to land not showing up…

Anyways, getting to the facts, you have two options to enable the new rendering more for WoW:

  • Look on your desktop or your favorite place from where you start the game – for your World of Warcraft shortcut. Right-click it, and select properties. Under the shortcut tab, add at the end of the line “-d3d11” (without quotes). Click Ok.

  • Alternately you can right-click your WoW shortcut and select “Open file location”. Go to your WTF folder, and double click the file “Config.wtf”. Open it with Notepad. Scroll at the end of the document, and add on a new line SET gxApi “d3d11”. Save your file.

Any time you want to go back to the way WoW renders graphics by default, just repeat the same procedure and remove the line you just added. Be sure the game isn’t already running while you are making changes!

That’s it! Some have experienced up to 40% performance increase in some zones, so happy gaming!
