Crossfire in crysis 3

Use full screen mode, not windowed. Crossfire only works in full screen mode, unless you're using Mantle & BF4 in which case it works in windowed mode, albeit with a slight performance hit. Either that or crossfire is not enabled correctly in CCC or did not activate for some reason when you launched the game.
I've just enabled v sync and it started working? Strange? It's in full screen mode , I've read that crossfire doesn't work in windowed mode , how much of a performance hit does it make on bf4 ? As I've had to enable v sync on that to stop the all mighty screen tearing haha
I expect the crossfire profile just didn't load when you started the game for some reason.
I get around 60% usage on each gpu so there is definitely a performance hit from using Mantle in windowed mode, however if you have fps spare like in my video below then it doesn't matter too much. The only way i can record Mantle gameplay is using Windowed mode below.
I recorded some BF4 Mantle single player footage using Borderless mode on my Youtube channel. (https://www.youtube.com/user/TheMattB81) Borderless means you don't have the desktop in the background like in the video above.

Now your just showing off with that fps.. What spec you have ? I have exact same settings as you but get around 100 fps and that's not in windows mode either ! Any idea on the gong evolved question?
That's not the full fps, that's missing 40% usage from each gpu, so well below normal full screen mode performance.
I'd reinstall your drivers maybe. Sounds like only one gpu is working to me. Use an overlay (and DX11 mode in BF4) to check out your usage and ensure both gpu's are getting 95%+ usage.
ah both my gpu's work in bf4 
... Just had a quick look at crysis 3 and there both working now like you said must not of loaded , thanks for the help ! That amd optimized app says I should run the game on high , but loaded it up and set all settings to max with no aa and it's like 50-90 fps which is good enough for me
