Low FPS with crossfire enabled

[amin45678]

I have a crossfire setup w/ two 7850s, an i5 3570k @ 4.2ghz, 850w PSU, Asrock Z77 Pro 4, 16gb DDR3 1333. Playing Battlefield 4 with Crossfire enabled gives me LOWER fps than if I were playing with Crossfire disabled. With only one card running I'm playing at around 55-80FPS. Crossfire turned on gets me in the low 30s to mid 40s. This is absolutely unacceptable and I don't see why it's like that. I thought Crossfire gives you BETTER performance. It's like this in BF3 also. I don't see a bottleneck here, and I have the latest drivers. Someone help me figure it out?

Actually I know the drivers are not the best from amd but you could be experiencing bottlenecking because 2 higher end cards in crossfire!!!!

try to use the AMD Catalyst 13.10 beta 2 drivers

By latest drivers do you mean 13.12?


It does sound like you have a problem. Crossfire performance in Battlefield 4 is usually pretty good

Yes but I'm about to try out the 13.10 drivers suggested by the guy above you. And yes I obviously do have a problem and it's really pissing me off because I see absolutely no reason for it to be like this.

Have you tried with Vsync on and off?
Have you tried with your CPU at stock speed?
Try disabling frame pacing

Try disabling ULPS

I don't know if any of these options will work but they have sorted the problem out for some people
Please try and report back

 

[amin45678]

I've tried with Vsync.
I've tried with the stock CPU already.
Disabling Frame Pacing doesn't help. Any other ideas?

 

[jay2577]

I'm all out of suggestions🙁
Hopefully someone else can help you
