For the record, I've seen a number of posts over the last year claiming that the login is doing nothing - which is clearly lacking any observation. The login graphics is live rendering the whole scene! It's just as prone to CPU/GPU burn as the main game is.
Here's my screen shots [http://i53.tinypic.com/s3j2p1.jpg with 85 Hz vsync capping] (pulling about 41% CPU usage, including all other tasks) and [http://i53.tinypic.com/2wh2e5w.jpg without vsync capping] (pulling around 106%).
I suggest concentrating on what is wrong, like poor framerate for example, rather than an unimportant side effect that doesn't impact game play or even any frilly bits.
