Keyclone FPS issues with PiP

[Nether]

Hello fellow mutli-boxers.
I have recently started dual-boxing two WoW accounts (RaF'd) and have been leveling toons. I started using keyclone in version 1.9g.
After recently updating to version 1.9i, I have been noticing some severe FPS issues. After hitting the PiP hotkey, the windows take a very long time to switch and the frame rate drops way below playable (no greater than 2 FPS o.o).

Now, I am by no means very knowledgable with Keyclone - I simply play WoW.
I did not have any issues prior to updating and can't seem to find a solution to my problem - I have done a lot of tinkering around in hopes I'd find some sort of solution but to no avail.

Any help is greatly appreciated as I am not too sure what could have possibly changed between versions to be causing such a severe FPS drop; it ran absolutely perfectly prior!

edit: After playing around a bit, I noticed that running the windows in full screen rather than windowed made a vast difference. Is there a way to have keyclone run WoW instances in full screen?
Apologies for my noobness!

It seems that it may just be a lack of computer resources. I dual-box on a dell m1530 - if I go down to 1280x800 it seems to work fine. If anyone has any suggestions for making it running smoother at 1440x900 that would be appreciated.

honestly you have to compensate in some way to run more wows on a system. Even the people who say 'I never lag in Dal' will also often note their FPS is around 30 and their Background FPS are capped at 10 or lower, some times down to 5. hehe. I would recommend not having the screens the same size maybe? If that is what you are doing, make one render in a small area (fill rate can help cause even if you are rendering 1440x900, if it only fills up an area 360x250 then the buffer flips are faster which are choke points in rendering. Lower some of the graphical settings on the window you are not looking at that often. If you are noticing some frame stops and hard drive grind than maybe setting up system links for your wow accounts if you have them copied over instead would help. You have to give a bit to get a bit in the end.
