set in ISBoxer, clicking on each slot, and manually changing the background FPS number. I found 20 FPS in the background
was good, 15 is great. I would not recommend going lower than 10 FPS in the background as WoW gets flakey at that point.
You can even turn the foreground FPS down to 50 if you don't mind losing out on that solid 60 FPS on your main screen.
You can also play with the CPU affinity listed in each of those slots. It is usually best to just make sure that all the cores are
selected which then lets Windows figure out which screen needs more CPU.
