Get out of the basement more often?
Seriously, though, WoW seems a bit.... dated. Like it is purposefully set towards those still running 1 Ghz processors, and no real graphics card. I know it is to maximize the population. . . However, there are limits. (At least that is what it looked like to me before the latest update.)
I was trying to put in a new graphics card, but it wasn't working, so i put it away without putting the old one in. I had a WoW cata raid that night, and out of impatience and curiousity, i decided to log onto WoW without a graphics card. To my surprise, i was running pretty much 30-40fps (not including the heavily populated city, where it would drop to maybe 3fps) and had no trouble with the raid.
If i can do that, i think the game might need an improvement in its graphics.
