You post on a thread about MP bf4. And you didint try to read the results.Yes bf4 is one of these cases
oh god i hate the trolls
If you dont understand my comment then just dont answer to me
Probably you dont get the fundamentals. Mantle actually atm helps only with cpu performance. And still even on SP bf4 you get lower performance with dx. And you post me a graph that bf4 doesnt scale at all no matter the freq and the cores.And then you tell me that i dont understand mantle
From 78 it went to 121. Not 66
That is my mistake on 66 vs 78. It is in fact 78 fps.

If BF4 isn't on of those games why does a 7850k + 290x show such improvement?
I know BF4 handles cpu much better than other games but still not enough in the 7850k's case.
This is where the 7850K individual IPC isn't strong enough and physically limits the game. My previous statement of i7 3970K, with a decent frequency at stock and twelve threads is the context of my claim. Also the retesting done by other sites show that the Intel architecture holds the game back a lot less than AMD CPUs.

says 75.5 FPS -> 119.3FPS this obviously shows a huge CPU BOTTLENECK with 290s in CF. Any questions?
The fact that is 75.5 FPS is the question. Which you all seem completely oblivious to me asking.
Here is an example of 2x 290/290xs killing Battlefield 3 in DirectX11.
Here is an example again of 2x 290/290xs killing Battlefield 3 in DirectX11.
A single Radeon R9 290X destroying Battlefield 3 in DirectX11.
But, alas, Battlefield 3 is not the same as Battlefield 4, how different can the results be?
Here is a single Radeon R9 290X doing quite well in BF4, DX11, Ultra:
Over the 78 FPS? Not quite, but this is a single card, not the 2x R9 290Xs in question. Ridiculous 75.5 fps. Any person here owning such a rig would question this without a second glance.
Here is another single Radeon R9 290X, higher rest, DX11, Ultra:
I dare say there is indeed a correlation, not necessary a cause or an effect, and nothing against Mantle, but the numbers are counter to what data we can actually find.
The DX11 performance provided in this benchmark and in DICE is below what I would come to expect of an 2x R9 290X, with varying degrees of changes. It is more than enough for me to question the accuracy of this test and DICEs test.
Factoriong in that the tests are un-repeatable. SO yes, I do still have questions.Edited by RagingCain - 2/23/14 at 5:10pm
