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.
You say the main runs at 1680x1050... are the clones running at 1680x1050 as well? You might want to set them to ~800x600 and limit the background fps.

EDIT: all instances of WoW render on the primary display, so using that second card doesn't help. in fact, it would actually lower performance in most cases.

I have a similar comp-- Q9550, 4GB ram, GTX 280... i have 4 clones on secondary monitor set to 800x600, fpsbk set to 15, maxfps 45 and i do fine unless i'm in a city, but i'm on 32-bit vista right now so i think the ram is a huge factor there. upgrading to 64-bit this week, and getting another 2 GB of memory too if all goes well. the funny thing is... having a gtx 280 on a 32-bit OS actually DECREASES performance in some areas because it has 1GB of memory... meaning the max system memory the OS can address is 3GB, shared between 5 WoW's and OS services, etc. I'm actually surprised that I get the performance I do considering haha
