Is it possible to turn down the video graphics on 3 of my instances of WoW and leave the 4th at the normal graphics? When I turn down the other 3 the changes take place on all 4. I run them all on the same computer and monitor hence the reason I would like one to be normal and the others to have their settings adjusted down to help performance.

On a side note: Y'all got me addicted quick. I went from running 2 accounts (Friday), then to 3, and now 4. My money my money ;(

Thanks in advanced.
