2x 8800GT performance weirdness?

Hey guys,

 

I have two video cards set up using aquamac's method, posted on a sticky by macgirl on this forum.

 

I'm running 2x eVGA 8800GT 512mb.

I have a Gigabyte ga-ex58-ud5 board. and was able to get both cards working with QE/CI showing as being enabled on sys profiler using the method above.

 

However, I noticed something really weird...

While both cards show up correctly on sys profiler, WoW works exceptionally well on my main monitor (PEG2), while WoW's frame rates drop quite a bit when I move the window to the secondary monitor (PEG1). The difference is very noticeable when I start changing my view angle rapidly.

 

I was wondering if anyone else was having similar issues where one card was performing better than another when they should be the same. I was also wondering if anyone knew the cause to this performance hit, since the same monitor & same video card should mean the same performance.

 

-Ryan
