My current specs are Windows XP running on Intel Core 2 Quad Q6600, GeForce 8800 GT, and 4gb of RAM.
For the longest time I've been running three clients on just one monitor. But since Wrath came out and I got flying mounts, and with the phasing, I've had some trouble where it would be nice to be able to see my secondaries and see if they actually broke /follow or if they were just going to warp over to me shortly, like they often do. So I hook up the second monitor, keep One on the main monitor and drag the other two over to the secondary monitor. My FPS went from sitting right up at 60 to down to around 10 or less. I expected a bit of a drop with having it display a second monitor and making all the windows visible, but this seems a bit much to me.
Is there anything I could do to try and improve it? Or what on my system would be the limiting factor that I could upgrade?
