Hi I have been having problems with BF3 and Crysis 3 working in crossfire. I know for a fact that in BF3 I would always get a steady 60fps with everything maxed out and vsync on now I am barely getting around 30fps. Same with Crysis 3 got it around a week ago and played with everything maxed and got around 47-60fps and now barely getting 30fps as well! All my other games such as BL2, Bioshock Infinite, and Tomb Raider all still get 60fps with vsync on. I have used Asus Gpu tweak to monitor my cards and both will get up to 100% gpu usage but says both cards are using 0% of memory... On BF3 I have turned down the settings to medium and it has had no effect. My video drivers are version 13.101.0.0

If anyone has any idea I welcome them. I just can't think of anything that could of caused this because all my other games still work fine just not BF3 and Crysis 3.

All my games run at 1080p and max settings with different AA tweaks depending on the game.

My pc specs:
AMD FX 8120 OC'ed to 4.0ghz
ASRock 970 extreme 3
2xGigabyte AMD Radeon HD 7850's 2 gb
8 gb ram
620watt power supply
Windows 8 64bit

Well it is a major fps drop from where it was but also textures seems to be taking longer to load . I never used to see it textures change from low guilty to high .

I don't know how important the bridge is to top performance on those cards, but make sure it is tight and on the right stabs.

Maybe eliminate a failing card. Remove one card completely and just run with CF disabled for awhile. Then swap out cards. Pay attention to the FPS of the cards. With both cards installed it is hard to tell which, if either, is the problem.

Ok just tried each card by itself on crysis 3 and both were getting a steady 21-26fps but with crossfire on only brought it up to around 27fps ... and bf3 each card by itself would be around 30fps and with crossfire it would go to 60fps with a lot of drops to 30 and 20 fps .
I tired tomb raider and borderlands 2 again on steam and both were staying at the 60fps mark.
