Hi ! =)

Since yesterday, I have got a Crossfire of HD 7850 OC, but my current experience is just horrible ..

 

You can see these screenshots taken on BF3 :

 

 

 

You can see stuttering, and huge lags (jerks). When I disable this technology, game is really smooth, no problem so far ...

I try to disable ULPS, but really little change.

 

I'm running on latest Beta drivers 13.8 taken on AMD website. I installed latest CAP 13.5.

 

My computer informations : 

 

  • AMD FX-8320 4Ghz + Cooler Master 212 Evo
  • GA-990XA-UD3 (Latest BIOS "FD")
  • CrossFireX HD 7850 Sapphire*2
  • Corsair Vengeance 2*4Go 1600Mhz CAS 9
  • Corsair GS-600
  • Windows 8 64x
My Temp, in game :
  • CPU : 50 - 55°C
  • GPU[1] : 60 - 62°C Max.
  • GPU[2] : 55 - 56°C Max.
  • HDD : 33°C
  • Motherboard : 35°C
I hope you could help me =)

For experiment...try un-installing completely (AMD utility/DriverFusion) and re-installing WITHOUT 13.5 CAP.

No change ='(

My both GPU are used at 50 - 55% on BF3 max.

You can see that : http://www.noelshack.com/2013-33-1376757500-screenshotwin32-0003.png

 

After reinstall 13.8 Catalyst, without CAP, GPU 2 is not used on BF3 : http://www.noelshack.com/2013-33-1376758555-screenshotwin32-0004.png

Sounds like a cpu bottleneck, check cpu usage in game, if its hitting 100% thats the issue.best thing to do is lower mesh quality in Bf3 options as it eats cpu.

I have 2 x 7870 and a 3570k @ 4.3 and I still hit 100% in Bf3  when it gets hectic, which causes the lag and stutter.

Try OCing the Cpu.
