FPS drops on second display

[Randyjohnson]

I just got a second monitor and I'm having some slight difficulties that maybe someone knows the answer to.

I have a 22" LG L227WTG as my primary monitor and a 22" LG W2252TQ as the secondary in extended mode running off a Sapphire Radeon 4870. Both are purely DVI connections and running at their native resolution of 1680x1050 @ 60Hz. I'm using the Cataylst 8.7 drivers but this was happening on the 8.6 as well.

I play World of Warcraft in windowed mode and on the primary display I get between 60-100 fps depending on where I am. If I try to move the WoW window to the second display my fps drops to around 17. Pretty much everything graphically is really slow on the second display. It's not the monitor because I've switched them around and whichever is plugged into the leftmost DVI connection on the card doesn't have a problem. I've tried making the other one the primary with Ultramon also it just seems like whichever is plugged into that left port works fine. I'm wondering if I have something configured wrong or maybe I have a bad card or what? I'm really new to dual monitors and their configurations so sorry if this is an easy fix. Thanks in advance.

My specs:
Athlon 64X2 5200+ @ 3.0
4GB Corsair Dominator 2 8500C5D
Asus M3A32-MVP Deluxe WiFi
Sapphire Radeon 4870

a couple wild guesses since you're not getting help:

* Have you tried changing the primary monitor with Windows' Display Properties?

* Have you tried changing the position of the monitors? I've been suspecting that the left monitor works better

* Not really a suggestion, but you should just decide on a set up where all your games are on your primary monitor. You can't move full screen games to the secondary monitor.

Enable Multi Display acceleration mode if available.
NVidia cards have this option, I dont have an ATI card here to check.
