Poor Crossfire Performance in BF3?

Saw you over on [H] as well. Hopefully one of the adjustments can help move things in the direction you want.

Stinks that 13.4 didn't do any better for you. Hopefully the CAPs are helping.

I don't think there's any CPU available that will allow you to keep 100+ FPS all will have dips in the 60s or less.

Well, thanks for all the answers. Looks like it's obvious, I also need a CPU upgrade. But for reference, I included a snippet from HWinfo log over 10 minutes:

Yes, CPU bottlenecks are the most annoying as they are the most expensive to fix, and if you already have a 3570k @ 4.5ghz as you do, then you basically have to dish out for ivy bridge-e when it comes out (for engines like Frostbite 2 and Cryengine 3 only, any engine that doesn't scale past 4 cores will show no improvement unless you have something significant running in the background).

Not everyone knows they have microstutter when they do. Look at this board. Look at you. But when review sites get gamer panels together, and have them compare, everyone sees a difference. I was the same way. Why should I not give him a tip on fixing something he is most likely experiencing and doesn't know it?

I'm not telling him he is having a bad time. I AM telling him how to have a better time.

Well you were wrong twice because he was already having a better time, so basically you were teaching him how to suck eggs, i already told you that he was not a noob, if you stop treating posters as if they are then you would not be telling them stuff that they already know twice.

CPU issue.

Turn Mesh quality down, it reduces CPU load and gains a good chunk of FPS on 64 player servers.

And you hardly notice the quality difference.

This turned out to be the biggest fix. Originally I had tried turning down mesh, but with Ultra settings otherwise, and I seemed to still be getting bad performance. Turns out that with one card, then it becomes a graphics bottleneck. All high except for low mesh is giving me good 1 card performance.

Thanks.

P.S. All hail the glorious PC gaming master race.

Woah that is strange, I wonder if I will have the same problem with my i7. I might test that once my second 7950 comes in next week.

Use HWInfo64 and let it log in the background as you're playing. Are you running a 120 Hz monitor? My 3570K has no issue holding 60 FPS ever, but at 120 Hz, 60 FPS isn't enough.
