It's not that simple. Game has to support it. And it would be very complicated and time consuming for someone who is not Blizzard to add support for that.
Blizzard did some test on 3.3.5 client before they released Cataclysm and you can enable it using config.wtf file. It is totally up to you if you wanna use it or not. Some people saw great improvement FPS wise.
1.) Open config.wtf file
2.) Add (SET gxApi "D3D9EX") without the parenthesis.
3.) Add (SET gxTextureCacheSize "X") without the parenthesis. On the X, enter your GPU memory size.
4.) Save
