Except shadows... Still does not work with any PC that can be bought with off the shelf parts.
I run with shadows on max on my SB i7 and have not noticed a fps dip from vsync other than occasionally in Orgrimmar and one time vs Maloriak in blackwing descent. Whether or not that was cpu or gpu bottleneck I won't know until I can do him again.
