Which is interesting, since DICE has posted CFX results with Mantle. They must have a different build of the driver?
Apparently. I haven't seen a single 290 or 290X user get crossfire working between here and OCN. Not in a stable fashion.

Neither have I, I'm just pointing it out. CF doesn't work for me in BF4 or in other games either. CF should show some excellent gains, reportedly.Apparently. I haven't seen a single 290 or 290X user get crossfire working between here and OCN. Not in a stable fashion.
Read my original statement.
Crossfire is broken in this release with 290 cards. It isn't possible to test. You may want to actually read the numerous documentations, user experiences, AMD's known issues list for this beta, or the article itself that brushes on this fact.

OK I disabled ULPS and check this.
DX11 - Shangie - looking at tower from the sea - 64 man server = 65fps.
MANTLE - same location and conditions = 143fps.
My CPU bottleneck is removed! My 290x's are now scaling perfectly!
W00t!!!!
It's definitely not a lie. From AMD's own release notes:Stop spreading lies, Crossfire works and has been tested by other sites.

I personally haven't been able to get CrossFire working in BF4 in either Mantle or DX11 renderers with 14.1. I get negative scaling (performance is worse with CF on than off).Intermittent stuttering or stability issues may occur when utilizing Mantle with AMD CrossFire™ technology in BattleField 4™ - AMD recommends using the DirectX code path when playing Battlefield 4 with multiple GPUs. A future AMD Catalyst release will resolve these issues

I'm not particularly impatient about Mantle. It's a beta and I'm not even playing much BF4 right now. I just pointed out that many people, including myself, have had issues with getting CF functional in Mantle. I'm surprised that one website got it working, since I tried a few different things, although I didn't go so far as to turn off ULPS or other driver features. Guess we'll see what comes out in the next few weeks.By all standard accounts a developer would have a working situation before the consumer. RIGHT!!! They could also share this working code with whomever they wish and under a disclosure agreement whom they shared it with may or may not be able to reveal that it is code that is not available to the general consumer.
How many times have driver been released that have fixed a problem but broken something else OR a supposed fix was taken out prior to the release because it was not where the company wanted it to be. For me it shows that they are working on a viable solution for the mainstream. Any new technology takes babysteps before it is mature. Just look how far surround gaming has come from the early days. Patience people, patience
many more than one have got it working.

I can assure you he is not lying. I have 290s in crossfire and not only was my entire system crashing when attempting to play under mantle,my directx performance was, without exaggeration, 30% of what I usually get. I rolled back to 13.12, and boom, my performance is back to normal. I attempted all sorts of troubleshooting, and nothing did me any good until I rolled back to 13.12
This thread brings to my mind the special type of fanboy, the CONVERT. This is the guy that used one brand for years then converted to the competitor brand. The zeal is strong in the CONVERT.
Those are two completely different technologies. A 290 can't use GSYNC anyways because GSYNC is only supported on NVIDIA hardware.So let me get this straight, at 2560x1440 with one card it is better to play on a GYSNC enabled moniter ( Asus one arriving shortly ) to keep games running smooth but on A 290 it is under 60fps with mantle and not as fluid unless lowering image quality settings such as AA?
lol I can see it now, new games come out, WOOT cant wait! 3 months later finally new driver I can play it now! oh damn got to wait on Mantel now.....2 months later WOOT Mantel updated ready to play my new 5 month old game! Crap 20-30fps what the hell, oh crap no CF support yet....... No thanks AMD!

You can play Battlefield 4 on AMD hardware right now, with existing drivers (13.12 works fine) in Direct3D, with generally better performance than on equivalent NVIDIA parts. I really don't see the issue here.lol I can see it now, new games come out, WOOT cant wait! 3 months later finally new driver I can play it now! oh damn got to wait on Mantel now.....2 months later WOOT Mantel updated ready to play my new 5 month old game!

Yes, it helps a lot in situations where the CPU is comparatively much slower than the GPU. It shows a pretty big benefit in APUs and other slower AMD parts. Probably not as much with the FX-8350.I wonder if the performance % would increase with an AMD CPU? AMD CPUs certainly need more help than a top end Intel CPU.
i am not trying to minimize anything.
I am directly refuting xoleras' hyperbolic assertion that its completly broken and no one has got it working.
Im sorry you are having issues
Lorien has posted a nice step by step to try:

Quick guide to get Mantle Crossfire working:
- Download DDU: http://forums.guru3d.com/showthread.php?t=379505
- Reboot/Start Windows in Safe mode, and use DDU to uninstall the previous AMD drivers.
- Reboot to Windows in normal mode.
- Install 14.1 driver (Run as Administrator)
- Reboot
- Delete all the folders in %user%/documents/battlefield 4
- Enable Crossfire in CCC (It also helps to disable ULPS).
- Start BF4 in Test range, and enable Mantle.
- Exit the game, and restart again in Test range.
- At this point you can change any graphics settings. Use resolution scale at least 125%
- Make sure Vsync is disabled
- If you want to make ANY changes to your graphics settings only do them in Test range do not do it while in game/match.
- Enjoy!
