BF4 Crossfire

[Mr.Wizard]

I have two radeon HD 7770's in crossfire running bf4. I am running the game on medium settings so i thought i would sell them and maybe get a 760 or 770. I then reallized, i should not be running this on medium like my friend who had a single 7770. I turned off crossfire AND WAS GETTING THE SAME FRAMERATE!! At this point i was enraged at the lack of performance and discipline my graphics cards had been raised with, i concluded that they must have been adopted.... ANYWAYS crossfire doesn't work in bf4 anyone else having this issue??? (yes i installed the beta 11 drivers)

Update your drivers?

[Mr.Wizard]

Beta drivers might be better optimized

Nevermind, BF4 doesn't support crossfire/SLI so they pretty much just screwed us over. I'll probably sell my 7770's annyone have a price suggestion?

 

Asus hd 7770 Ghz edition direct CU bought them for $140 each last summer in july

But... it does. A title as big as Battlefield 4 of all things, why on Earth wouldn't it support SLI/crossfire. 

 

It's a problem on your side.

 

Sounds like yours crossfire was never working in the first place and you've had a $140 GPU sitting there doing nothing for a long time.

[Mr.Wizard]

Sorry, turns out I just found a red herring, Crossfire is definitely is supported, yet i still can't get it to work, i found that when it was enabled and i ran bf4 one of my gpu's will run about 15 degrees cooler than the other (hope that helps)
 

Edit: I think it is my ULPS, i'm gonna try disabling that beacause it works every now and again, but not always

I had 2x7870's in crossfire working fine in BF4 (1080p, ultra, 60-100FPS) so crossfire definitely works. youre not playing in windowed mode... right?

im having the same issue i have 2x 290x both watercooled i get 50fps ultra and wont fall below 45 on 1 card, 2 cards it drops very low and maybe hits 60 fps at pointsand 30fps on low far better on 1 card i have 9.2 drivers couple versios below the newest as the drivers wig out my sound. both cards are working only sitting around 50-60 degrees

i have a single card and i get 60-80 fps on ultra so i dont think it is properly supported

Check the crossfire bridge cable. After I tried a different one it work perfectly.

Alright, now that you have given the game some time, recheck you settings in drivers, try again, and get back to us. EA/BF4 are huge partners with AMD like our friends here mentioned, SLi and CFx are supported no matter what, only difference is that the game or your settings (in drivers that you may have changed) are giving bad scaling performance form cfx, as of right now.

if you were to sell them I would be interested. I have a single Sapphire Vapor-X OC HD7770 and I can run BF4 on medium with 80fps. High I get 40-50.

i have two sapphire radeon HD 6950s running in crossfire, it definitly works, both of them show about 98% usage, check if your running the game in borderless windowed mode, i was trying to find a way to force crossfire in windowed mode, but sofar i can't so if you're in windowed mode, go into full screen.

 

other than that, if you have duel monitors, you can put MSI afturburner's hardware monitor up on it and see if the second one is being used, if you don't, there is a second command you can put in the game (`) that will show you what the game uses, i don't know it off the top of my head, ill have to double check.

 

for example (i was using it) when i was in windowed, it showed only to see 1 GPU, but when i went to full screen, it saw the second one.
