Interesting, thanks for the ideas.

Not sure my box is powerful enough to raise the maxfpsbk without affecting overall performance. I have a dual core athlon x2 2.2GHz, 3GB of DDR2-800 (pc 6400), and an 8600GT. The aspect ratio is the same for all 5 wow instances, 1024x768 for the main and 800x600 for the other 4.

I guess I'm just curious what the resolution input at the bottom next to "enable maximizer" actually does? I have that set to 800x600 on all my clones but they still become 1024x768 when I switch to them using PiP (cause my main region is 1024x768).
