I hear a lot of people get horrible FPS in Dalaran. I think the best solution is to upgrade to a 64 bit OS and then get 8 gigs or better of memory. I bought a new i7 processor based computer with vista 64 and upgraded the memory to a total of 9 gigs and I have no issues at all with lag or FPS. Even raids on cities don't slow me down. With 8 gigs of memory you literally have enough storage in memory where you don't even need a hard disk swap file. I really don't think there are a lot of workarounds that would make enough of a difference with Dalaran. Shatt maybe but not this baby.
