--------------------------------------------------------------------------------
For those that are affected by this Error 132 (unsupported and supported cards both), you can get around that error by setting your texture quality to 'high'. To do this, go to your World of Warcraft folder and open the WTF folder. Open the config.wtf file in Wordpad, then look for this line:
SET baseMip "1"
If that exists, change it to a "0". If that doesn't exist, copy and paste this line to the bottom of the file:
SET baseMip "0"
Save the file and try the game. A low quality texture fix will come in a future patch.
A fix to this is coming in a future patch.
NOTE: If you reopen the "config.wtf" file after making changes, you may not actually see all the lines you added, but this is normal. It does not necessarily mean the game has not saved them in its own data files.
Update
S3 people and others with a related Error 132 crash - you may want to install the latest motherboard chipset drivers as well as the video card drivers. Development and the QA teams will be trying to reproduce the bug on the S3 UniChrome since it seems to happen most often there and seems to be related enough to other non-related cards. If it can be reproduced, they can work on a solution. They will be using the latest available drivers so you'll want those too to be on the same page.
If you need help finding the chipset drivers, check this -
