Blizzard has announced the release of the latest patch for World of Warcraft, bringing the game up to version 1.2.1. Of note to Mac gamers is that the new patch now enables vertex and pixel shaders for certain Mac systems thanks to the recently released Mac OS X 10.3.7 that includes updated NVIDIA and ATI graphic drivers.

Here are the Mac specific changes, as note in the change log:

• The vertex and pixel shader based graphic options have been reactivated on certain combinations of drivers and GPU hardware. As Apple releases future improvements to drivers we will continue to re-test and re-activate features on a case by case basis. A more detailed list of which driver/hardware combinations are enabled for shader capabilities, along with any known bugs will be posted on the Tech Support forum. Further optimization work on the client is ongoing, and we welcome your feedback at wowmacteam123@blizzard.com.

• Added reverb to sound effects when a player is in enclosed spaces.

To download the 1.2.1 update, simply connect to World of Warcraft and the patch will be automatically downloaded and applied.
