You need to obscure your email account login info in that pic. ;)

In that pic, do you see the Name and Value boxes bottom right?

Click "New" above them.

For maximum foreground window FPS of 10:
Name: maxfps
Value: 10

For max background window FPS of 10:
Name: maxfpsbk
Value: 10


Then load your WoW clients and they should all use the desired settings.
