Not sure if this belongs here, or in the gaming forum, but I'll start it here first. After reading up on the WoW threads about getting best performance from my core duo mbp, I think I got it all tweaked up nicely. I was getting a nice 30-40fps outside, and 60ish inside, which was a good balance between quality and performance. But after doing some other things on my computer for a while (torrents, music, surfing, adium etc... the usual) I started up WoW again to find 10-15fps as the average. I tried everything I could think of, then gave up and gave it the old windows-style-restart-fixes-everything fix, which seems to have done it. So my question is what was slowing my computer down. Since it goes to reason other parts besides wow were running at close to 50% of their full speed, what was causing it? My cpu usage was below 5%, ram was fairly empty, nothing was open. Ideas?
