I have a beefy rig. Vista 64 ultimate..8 gigs of DDR3 ram and a 280GTX card. I play 5 accounts everyday, all day with next to zero lag and 60+ FPS on my main window. Just today i log in and am running very slow on all windows when i have more than 3 logged in.

I have tried all the things i know. I disabled all addons, turned off sound..set everyone on min setting..ect. I Seem to only slow down when I have 4 or 5 running now. I'm wondering if anyone knows when i might have went bad. I logged into Far Cry2.. have everything on max and run smooth like butter at 45+ FPS. It seems its something to do with multi windows of wow ( after 3 ) And ideas?
