Crossfire 6850s not putting out what they should

post #1 of 3
Thread Starter 
I have a rather strange problem with my crossfire setup. When I first start a game my graphics cards are at 85-100% usage each as they should be, but then they seem to randomly drop off to about 40% each and my frame rate drops like a rock. I know my processor isn't bottle necking as this happens in games where only 75% of my processor is being used across all cores. I have already re installed all of my ATI/AMD drivers, and installed the new 12.1 preview. Any Ideas as to why my cards are not being used to their full potential?

are you using only one 22" monitor?
two HD6850s would be overpowered for a single monitor even at 1080p.

Try using 3 monitors to see 90% gpu usage.

I see what you mean but shouldn't my graphics cards be giving me the best frame rate that they can. When I first load up a game in BF3 the usage is high and I get a great frame rate but after a few minutes the usage goes way down, and if I turn down my settings the usage only goes down even more. Is their anything that I could have installed that could be limiting my graphics cards?
