Ok so i have had my radeon hd 7850 for a while now and i decided to get another instead of upgrading to another video card. I have had this second card for a month now and i have not seen a single increase in fps in anything(one card is at 99% usage the other is at 0%) (BF3, BF4) so the first couple of days i went searching around for solutions, none of them worked unfortantly so after a month i am now having to ask for solutions here.

Specs:

Video Card: Radeon HD 7850 1GB x2
Processor: AMD FX-8320 4.2ghz watercooled
PSU: 750 Watts
Mobo: TA970

If anyone wants to know i already have crossfire enabled


Anyone know what the problem is?

have you tried running some benchmark program just to see if there is performance difference between a single gpu and crossfire enabled?

yes, there was a performance increase and they were both at 99% usage, but in games it does not work and the second card idles.

it didn't work with any(i usually play BF4 and BF3 which is where it matters the most), i actually found out that i get more fps without the crossfire than with it.

well it's weird if crossfire are not working with such popular games. the fact it was able to run benchmark program just fine shows that the hardware were working properly. what about older drivers? or maybe you need to clean install the driver
