Hi,
I am getting low gpu usage in BF4, BF3 and other games. My GPUs are a 7870tahiti in crossfire with a 7950. My CPU is a stock FX 8320. The GPUs run at around 30% usage and the CPU at around 70%. I just added the 7950 a week ago and did not reinstall the drivers. I might end up doing that as that might be the problem, although I doubt that it is the culprit. I called EA and they could not help me. When I changed the res-scale from 25% to 200% there was no FPS difference, the only difference is going from Ultra to Low. I intend to run the game on Ultra @1080p with 200% res-scaling. Please help me as I have no clue on what to do.

Thanks

what motherboard are you using? theres a solid chance that your mobo is only capable of PCIE 8x8x4x when 3 cards are in use, the 4x slot being a pretty severe bottleneck. to test this theory, put the 7950 in the top slot with the additional cards below it. if the FPS increases, thats your problem. of course, you could always look up what your motherboard is electrically capable of providing for the PCIE slots

Asrock 970 extreme 3 r2.0. It is already there, and the problem, I just found out only affects BF4.

Thanks for your reply.

I have only two. And yes I think so. I CF I'm getting very unsable FPS and very large FPS drops. Also I fixed it for other games. The GPU usage it better now but the FPS is still low.
