ATI 11.3 CF Cocern

post #1 of 9
Thread Starter 
Ok so recently with BC2 Ive been testing it with and without CF enabled. I have 4890CF, Q6600@3.6, and 8 gb of ddr2(everythign else is in sig). Tell me how this makes sense please...When CF is enabled i get average of 35 FPS (recorded with fraps). When CF is disabled ive been getting into the mid 60's. Both tests have been used in a full server under similar conditions. anyone have any idea why it seems that my 4890 is performing better when not crossfired???

Swap cards and see if both are performing equally.

Check if either of the cards are overheating. Can easily cause massive performance loss.

I swapped the cards and noticed the same issues. With the current driver. Basically just with cf off it performs better that seems impossible

from what I have been reading on this forum and others. CF seems to be really hit and miss with certain cards. Not sure why.
