Most likely this is because of the changes they made to shadows on Ultra. It was in the patch notes somewhere near the bottom I believe.

That's because the max Shadow setting was bugged, and wasn't clipping shadows that weren't visible. I'll bet you enjoyed your 10 FPS in Dalaran.

Sorry I need more caffeine. The way I read your comment the 1st time I thought you were confused as too why your FPS doubled :P

I know why it changed, but I was just stating that I was happy it did. Of course, no one's computer could escape the lag last night that happened on my server in Dalaran (Kirin Tor). The jewelcrafting vendor and emblem vendors were swamped by half the server and even if you got a click in, then it would lag for the next minute-and-a-half.

Actually, the information is very valuable to them because, otherwise, they would have to pay a research company a lot of money to gather this for them. And, of course, not only we are giving it for free, but we are actually doing that while paying to pay the game.

I know that we would be paying for it one way or another (if they were paying for the information, the price would filter down to us in the end), so it is all the same in the end.
