Using 2nd GPU for wow instances (Fixed)

I take it this doesnt work if you are using one monitor with PIP?

I'm not sure how a monitor could use two cards, does the monitor have a mode that just makes it appear as two monitors? If so then I'd guess this would work fine... I'd wager this is something specific to the massive resolution of the 30" monitors right?

eh I'll just get another monitor =)

Hmm, does this mean I can bung my older 8800GTX into my new system alongside my GTX285, run my two screens from separate graphics card and get pretty good framerates out of all five WoW clients?

I wonder if my 650W PSU can handle it...

I believe (and could be totally wrong) that you have to have Vista or win 7 to do this properly as Xp cannot do "something" with two video cards, I'm sure someone more knowledgeable will chime in

Vista didn't handle this for crap.

Windows 7 handled it.

Are you able to open a single wow session, put it in a window, turn on FPS. Should be like 50 or what ever you usually have it on - and move it aroudn to each and every monitor?

In Vista when a single pixel moves into a monitor from the secondary GPU the frame rate drops to like 10 or so. Move it back to the primary GPU and frame rate recovers.

If you can move it around with no problems then it will tell us for sure if Windows 7 fixes the whole secondary GPU not-rendering thing.

I'm not sure if I'm adding anything to this discussion but I wanted to 3box (eventually 5 if I can) without using another pc or squeezing windows on my existing monitors. I have a spare 19" so I brought an nvidia 8400 512mg pci (only slot i had available) and popped it in. Win 7 RC 32 (I'll be installing 64) recognized the card after a reboot and I setup the 3rd monitor. I configured keyclone and ran 3 windows of wow from 3 different folders on different harddrives. I can move the 3rd window around all of the monitors without seeing fps hits but I usually run my slaves at 20fps anyway. withouth much further testing the only thing I noticed was that I couldn't run it full screen (monitor was 1280x1024) so the window was only running at 1024x800. My main vid card is an Nvidia 8800 running the main window at 1920 on a 28" monitor and my second slave on a 20" widescreen running 1024x800 full screen.

I only have 3gigs of ram but running 3 wow's I still had about a gig of ram free so not sure if that hampered my performace or not.

What should I do to test if the 2nd gpu is being used by Wow?

Setting a monitor to "primary" and then launching wow does indeed allow the usage of other GPUS. I have not found a program that will automate/help this process. It is simply too clunky imho.

I'm in the process of testing out innerspace and isboxer. Lots of more options and a learning curve to overcome.

Are you using Windows 7RC1 or something older?
