3. make sure to set your maxfpsbk and maxfps to reduce system load
4. reduce your details ( http://www.dual-boxing.com/wiki/inde...phics_Settings ) to save cpu/gpu
5. make sure you have enough system memory. rule of thumb: OS + nWoWs * 500M (OS xp == ~500M, vista == ~750M)
What does maxfpsbk do?

Sounds like max fps for wow when not the focus in windows.
