One quick fix that I can think of is reduce the resolution yeh play at.

Do you have the sound off on the all the others I think there's an option if its in the background the sound is off.

KIll the affects, biggest one is view distance.

Yeh can reduce the max fps for the background one as low as 5 maybe lower but never tried.

Another thing that'll help a lil is kill some services.

running anything else in the background?


The thing is that from every new area yeh go to starter area/old zone/bc/wotlk each zone requires more memory with dalaran being the worst area.

You can get away with 4 gigs of memory, 5Xwow with XP but vista needs more.
