WoW Performance Patch for PPC Macs
6:55 AM | Cord Kruse | 5 comments

The latest patch for World of Warcraft, version 1.12.1, offers owners of PPC Macs an optional feature which may smooth out frame rates. A developer post on Blizzard's forums explains how to make the change, which requires use of the Terminal to create a preferences file.

Many in the forum are reporting huge improvements in framerates. Here's a step by step run down of the process:

A. copy the three lines of text below onto your clipboard (select then hit Command-C). The first line is the "cat" command, the last line has the "4" on it.

cat > ~/Library/Preferences/com.blizzard.Internal.prefs
#Current User\Internal\VBBMODE
4

B. open Terminal.app (in Applications/Utilities) and it should provide you with a UNIX command prompt. What we're going to do is paste the text in above, which will ask the command line to create a file in your preferences directory named "com.blizzard.Internal.prefs", and will inject the two lines of text after it into that file. We're asking WoW to use "vertex buffer broker mode 4" which is the new code for PowerPC systems.
C. Paste the copied text into Terminal. (Command V).
D. Now hit Control-D (not Command-D). Control-D concludes the command we started in step C and closes the file.

E. All done ! Start WoW and see how it runs.

Considered to be in "beta form," the graphics tweak is not recommended for Intel Mac owners, and is targeted at PPC Macs with more than 512 MB of Ram installed.
