Crossfire 7870 users - how many FPS are you getting in Battlefield 4?

As the title says, what are your FPS, specs, and drivers? Whenever I'm in a multiplayer match, crossfire becomes retarded and I get less performance than one card with huge lag spikes (DX or Mantle). When I load up test range it runs very smoothly in DX (but not Mantle) despite the patch note:

Mantle: Multi-GPU configurations (up to 4 GPUs) running Battlefield 4 are now supported

I know the drivers are still in beta, but then again how do you explain this: http://www.youtube.com/watch?v=KSPEPwsqZq4&list=UUZAHhaXOH7xVuyDLslA_w2g

:??:

My specs:
AMD FX-8320 3.5GHz @ stock
Asus M5A99X Evo R2.0
8GB Corsair Vengeance 1600
2 X Radeon 7870
OCZ 600W StealthXStream

Drivers:
14.2 Beta

  1. Assuming a overclocked ( 1200mhz core clock, 1480mhz memory clock ) 270X is give or take a 7870/7950
    I get avg 60, but dips to 38-45 at times, high settings, 1920x1080.
  2. FX8320@4.2 /7870xt 2gb @1200/6000, 16gb corsair 1600mhz, m5a97 pro, 550w ocz S i use vsync and only it dips below 60 to 45-50 on high settings, if you are trying ultra settings your cards still only have 2gb of vram between them, ultra setting might be filling your buffer, what setting and res you use ?, what do u get,
  3. Best answer
    Both of you guys are apparently using just one card, because that's about the performance I get with a single 7870. I currently run this game on its lowest settings @ 1080p for the performance, but I was hoping for similar framerates on Ultra settings with Mantle and Crossfire.
  4. yeah sorry im too poor to buy 2 cards :P,
    are both your cards running at exactly the same clock speed ?, is it only bf4 you have issues with? , start off by using msi afterburner and have it sync clocks for both cards and force constant voltage, go to amd overdrive and push the powerlimit to 8%, if these settings do not work try uninstalling your card drivers and installing them again, make sure there are no chipset drivers missing for your pc i use "slim drivers" app its free and it works....... you could try switching them around the graphics cards i mean
