All WoW's graphics settings are set to minimum, but performance is
still pretty terrible though. Although WoW's FPS meter is reading about
50fps in both windows, I think it's actually about 10fps really. I know
the second machine is pretty weak, but is there anything I can do to
boost the fps? I've got new hardware on order, so this would just be
for the interim. then cast the spell.
Keyclone allows you to set the max/min fps per client. I'm not sure how you go about doing this without it, but you should see a major improvement when setting it around 25 or so. I think you can set max fps in of the ini files.
