My desktop with 512MB of memory and a GF4Ti4600 128MB runs it fine mostly at medium settings, though it goes down to .5 FPS when I first enter Orgrimmar by fast travel (but picks up to a playable-in-non-combat 14-20 FPS after a few seconds), and has an unexplainable drop to 5 FPS in Crossroads. Also, I've noticed that the game seems to be in texture-memory-saving mode, as the terrain is composed of 40 meterx40 meter blocks of texture without transition and sometimes player models are white. I get my laptop (Radeon 9000 512MB,1GB system memory) back tomorrow; I can't wait for WoW to look pretty again, not to mention being able to check thottbot while I play.
