I could also use some bigger screenshots because latency and frame times arent readable on those that you posted.
how is your ulps? disabled? enabled? are you using overdrive in ccc or pure afterburner oc?
how are your chipset drivers? up to date?
how is gaming on one card?
are you using vsync? because strangely on your screenshot you seem to hover around 57fps. and vsync is bugged in cf in latest drivers
If you right click the images and open them in new tab it should display at original resolution (1440p).
I only have one monitor, vsync is off but frames are limited to 62 via the fps command in BF4 (Unlimites framerate gives same issues). Showing 57 is just a coincidence, sometimes it hovers well below 40s even 30s fps.
ULPS is disabled, cards are at stock (tried power target to 50 percent too).
CPU is not choking, all cores are well below the 60-70 percent of usage.
Gaming on one card (CFX disabled in CCC) is just fine. Gaming in Windowed mode to use one card but CFX enabled in CCC gives as crap results as fullscreen with two gpus.
MSI AB shows RAM usage has high as 6GB overall (BF4 uses around 2-2.8GB) but it showed Pagefile as big as 11GB! Memory leak? Or that Pagefile size is normal?
By the way, I tried closing ALL software but Origin and Chrome with Battlelog, and issue still happens.
It only happens with BF3 and BF4, any other game runs completely fine, so I'd blame it on either AMD Drivers not having decent profiles for these two games on R9 CFX cards, or DICE broke it.
I've already reported this thread to AMD and hopefully they find a solution either on their own or together with DICE.
