60% cpu usage BF4

[VG Docs]

Vsync limits BF4 to 60 FPS not 30

It does depend on the monitor. To be fair though, it's unlikely he's running a 30 hz monitor.

nvm I tried with out CF and i get 90fps 

how's the experience with other games? Is this issue isolated to BF4 or does crossfire have issues for you in other games?

[C1intFunWood]

No (user of two 290x's)

On topic: check crossfire is enabled. But TBH one 290 is more than enough to ultra BF4 @ 60fps using D3D/Mantle

I use 2 cause I use 200% scaling

[Jodomcfrodo]

Does it ever drop below 30? I know EVGA (don't know if this applies for AMD) has a fps limit so to not cause screen tearing and extra power. Also maybe thermal throttling they're reference... BF4 has a FPS limit console command as well. 

 

Also, did you buy these cards for $40 from china?

 

Edit: Just read the recent comments... IDEK what to say about that...

I was saying something like Vsync since in one of my games there's an option to limit it to 30FPS.

You were playing without Crossfire enabled?

 

Now enable the Mantle API in game and enjoy your 40% performance boost in BF4

lol thats not how crossfire scaling works...

youre lucky if you even get a 60% improvement

Well that may have been problem right there.

scaling as in res.

ah ok then

[PhantomChevron]

Catalyst 14.1

Dude the latest stable one is 14.4

[SkilledRebuilds]

Back off your resolution scaling a little, and then put it back up, see if there is any weird bugs in the memory management, when I was using scaling, I was seeing a 40% fps drop no matter if it was 110% or 200%, but then if say, after a restart, I oculd use 150% for a whole game and it was playable fine,.. as in its probably got its own set of problems that don't arise often enough (because a lot of people don't use it)

 

So have a play with the scaling?

[Bendystraww]

Even at 90 fps I wouldn't be satisfied after spending the money for two 290s, Shouldn't that be a solid 120+??

[nosirrah123]

Bottleneck?

No, 4670k would never bottleneck BF4 at 30fps ultra. 2 290's should be pushing at like 3000 fps.

Not in this case. I have tested it and you gain closer to a 80-90% FPS boost.
