I have a new Unibody Macbook Pro. The game runs perfectly on the 9400 UNTIL I set foot into Dalaran. The game begins to slow down and eventually hits about 1 FPS and does not improve upon leaving. To test this FPS decay, I tried hearthing to the inn in Dalaran and then immediately taking a flight to Dragonblight. My FPS was about 54 when I started the flight, but it hit about 3 FPS a minute later. The very act of being in Dalaran seems to "infect" my card, causing it to slow down over the course of a minute (something like a memory leak, maybe?)

When I use the 9600, these problems largely disappear (Some symptoms are still observed. The frames occasionally jerk in Dalaran).

I'm not using any addons. The system isn't hot (even with the 9600). The problem is not a function of how long I'm logged in.

Anyone have any ideas/similar experience?

Greetings, All!

Some blue news:

Addons - Remove them. QuestHelper's notorious for this exact issue.

Updates are your friends. If you haven't done so recently, run Software Updates and make sure you have the latest & greatest.

(If you have 10.5.5 already, do the combo found here:

Is this isolated to ~just~ Dalaran?

Q u o t e:
Hey everyone,

Just got my new MBP today: 2.8GhZ, 4GB Ram, 320 GB HDD @ 7200 RPM.

Dalaran is my bane. I have three characters across two accounts in Dalaran. None of them allow me to log into the game. I keep getting a "Disconnected from Server" message. One character allows me to log-in only to see a completely lagged out scene with people running in place etc... 30 seconds later I am kicked off.

...
Also, I have an existing PowerMac G5 that I also has WoW. I can successfully log into WoW with the aforementioned characters on the G5. Indeed, I used the old computer to move my main out of Dalaran (into Agmar's Hammer).

Having done that, I tried to log into him from the new MBP... I can login, but there is major lag... I can play after a bit with the lag going down incrementally. I fly back to Dalaran and things fall to waste. Major lag and I get booted shortly thereafter.

Has anyone encountered this problem?

Can you describe in detail your network setup, and what method each machine is using to connect to the net ? (ethernet, wifi, etc)

Those junk routers are still out there, like mines floating beneath the surface of the sea...

So, you have a portable computer - have you thought of picking it up and trying a different network connection somewhere?

Apple stores have free wifi..
