I would have grave suspicions about timing and synchronization errors as the
draw functions return much sooner that programs expect them to and also return
before anything is actually drawn. This could also lead to games falsely
claiming higher FPS that is actually shown in cases where you can accept 100
frames per second worth of draw requests, but you can't actually manage to show
all of them in that time, so the queue just grows until you start getting huge
latency between an action happening in the game and actually showing up on the
screen. 
The games measure FPS exactly for the purpose of preventing that - frames are
dropped so that the time between an action happening in the game engine and
showing it on screen is never delayed by a queue of frames to be rendered.

I'd rather see the multi-core identification issue fully solved. If WoW does
not manage to figure out that there is more than one core, then they actually
turn off all the multi-core optimizations that they already have in there.
