Hi, I have an ATI Radeon 6950 and have just bought a 6970 along with a crossfire bridge. After fitting the new card and the bridge, I've enable crossfire in CCC and downloaded and installed the application profiles, restarted my computer and fired up BF3.
After finding that I haven't had any kind of FPS boost, I downloaded AMD System Monitor, and ran it during BF3, but the graph shows that each card is only using about 45%-50% of its GPU? When I turn crossfire off and disable the second card, the graph shows that the one card is using about 80%-90% GPU. Can anyone please help me understand why this is? Shouldn't they both be pushing up to atleast 80% and giving me a much greater performance boost?
My other specs:
Windows 7 64-bit Ultimate
AMD Phenom II x4 840 @ ~3.2GHz
16GB DDR3 Ram - I think its at 1333MHz
Oh, so your saying that the graphic cards are being held back by the CPU? Let's say I upgraded to a 6 core running at about the same speed, do you think that would be likely to increase the performance much?
