With InnerSpace, I don't need to use Symbolic Links or Junction Points, as the config file is virtualized for each toon. Different settings per account, is about the only boost from linking to the same folder. Referencing a file several times isn't any faster then just using that file each time. The program worked great for me too; it's found here: http://schinagl.priv.at/nt/hardlinks...kshellext.html

I've got a Sapphire 4870 X2, and run each of the wow's with shadows all the way down. Aside from the event where you needed to catch the torches, by standing in the shadow of them... shadows don't do much in wow, aside from kill frames per second. Pretty much, slaves have every setting down. And the master toon has maxed view distance and spell effects.
