Different FPS depending on Screen? - Multiboxing in World of Warcraft and Beyond!

TwentyTotems · 11-23-2009, 09:13 AM

I have stumbled across a strange issue which I can explain nor solve:

I have been running Windows Vista home (32bit) for a while and I just upgraded to Windows 7 Ultimate (64bit) ... and now my WoW's are loosing fps if I run them on my secondary screen?

I move my wow-window to my primary screen and the FPS goes up ... I move my wow-window back to my secondary screen and my FPS drops (even lower to what I previously had on my Vista setup).

Any idea's ... anyone?? Any suggestions are welcome.

Hmm. Is the refresh rate on your second monitor lower than your primary one? The issue also might have to do with resolution of your secondary monitor.

Same refresh rate on both screens (and in wow): 60Hz ... same resolution on both screens 1280x1024 ... nVidia 8800 GT btw.

Hmm, your taskbar wouldn't be on the secondary monitor by any chance, would it?

Nope ... taskbar on primary screen.

i am not sure, nor do I know the technical reason, but it has to do with the secondary monitor not being the "focus".

So if you are playing on main monitor and have slaves on secondary monitor, the slaves on the second monitor are limited to 30FPS, at least for me it does. I am running windows 7 x64 ultimate and still have this problem. Not sure if there is a fix or not out there for the problem.

The primary monitor gets priority access to the GPU. Naturally, the secondary monitor will get lower throughput if there arent enough resources to go around.

LL is 100% correct here. I went through extensive testing on this back when I was originally doing my broadcast and playing 10x WoWs at once.

In this case be better to have SLI/Quad setup.
