Hello all,

I just got bought a GTX260 card and added to my machine to sit next to my 8800GT. I have 2 monitors, a 21inch plugged into my GTX and a 19inch plugged into my GT. I am running Vista 64bit, 4GB ram, Q6600. I have Nvidia 178.24 drivers.

My main runs on the 21inch at 1680x1050 and my clones all share the 19inch. All wows are in windowed mode.

With my main by itself, I get about 80fps. What I am finding is that the mains fps gets really low (about 20) when I load the clones up.

Can anyone explain to me why this is happening? What is vista doing? Is this FPS to be expected for such a system?

Thanks in advance for any responses.
