We are putting the finishing touches on the AMD Catalyst 14.1 Beta driver, which enables support for Mantle. We appreciate your patience.
I'm just going by what I personally have done, and AMD's screenshots.
Anyway, I re-tested that area and sure enough, AMD had taken screenshots during grenade explosions, which explains the red hue and all that.
And yes, there was a frame rate drop, although not drastic depending on how close it was. If it was a direct hit, the frame rate would drop into the 80s.
If it was close but not direct, then frame rate would stay above 100 FPS, but below 110 FPS.
Judging by AMD's screenshots, I can tell the grenade explosions weren't direct hits because there are no injury indications on screen ie blood splatter.
And what did Microsoft contribute to DirectX? Only the include header files and docs?
Direct3D definitely has it's inefficiencies, but NVidia has seemingly managed to work around it fairly well, while AMD hasn't.
Take DX11 multithreading for example. NVidia has this feature enabled in it's drivers, and it has resulted in very large performance gains in games that use it; best example being Civ 5.
AMD on the other hand doesn't have it enabled after how many years now, and by all reports, tried to implement it but could not get it to work properly. It either gave them no performance benefit, or worse, a performance decrease.

OK I did some checking, and you are right. I think that particular scene had a workload that used 4 cores, so that would put it around 3.5 to 3.7ghz..
Look at recent benchmarks of Civ 5. AMD isn't as far behind as to call it a very large performance gain anymore.
You're doing it wrong. You're comparing your OCed CPU dealing with frames at a rate of 9.30 ms (107 FPS) with a stock CPU dealing with frames at a rate of 13.24 ms (75 FPS).
Are your prices in line with the US before the "mining tax"? Also I seem to remember that some of the world doesn't have real access to computer hardware in their home country no? Like some people have to order from elsewhere? Probably a small percentage.
I am not really familiar with how supply and pricing is in Europe for example.
I think the perf overlay is adding the times of both GPUs so it would be massively CPU bound in the first screen and slightly CPU bound in the second (14.02/2=7.01 < 8.38).
Honestly, I'm probably going to run my CPU at stock clocks and see what kind of performance I get..
That's the only way I'll know for sure..
Well, they aren't in line cause I live in a 3rd world country, but as a comparison.

So that is U$815 for a GTX780
U$993 for GTX780 Ti
U$721 for R9 290
But they are as they should be. 290 cheaper than 780.
Could that be caused by AFR, so that each frame takes longer, but drawing them in CF doubles fps?
For those of you with beefy CPUs where the GPU is the limiting factor, AMD says don't get your hopes up. It writes, "An API change is unlikely to make a drastic change in these scenarios, as GPU resources are being maximally utilized in a fashion that is difficult to improve at the API-level."
True, but not in BF4. The Frostbite engine uses it's own sound drivers.I don't know everything about TrueAudio, but if this tech help to reduce CPU bottlenecks on games will be all good to PC gaming scene.
Who in the world would pair those? So basically Mantle wasn't made for enthusiasts, yet it was beat to death on this enthusiast board.

No thank you.
Download the star swarm rts engine demo on steam guys!
I am running on dx now. That is some serious rts engine we have there. A lot of stuff going on. Thats some change for the rts games comming for sure on dx as well. Some serious multicore coding for sure! What a blast of a tower defence game this engine could make.
Now we just need the mantle drivers - yeaaa
