So there's no point in installing this now if you don't have BF4?
Until Thief 4 comes out? Not really no. Not unless you're like me and want to see the pretty numbers when you do the star swarm stress test.

I thought the 7970 doesn't have any mantle support yet? , everyone saying it feels different with that card is pure placebo.

I see a difference with my 7950. It just seems smoother. Unless I'm crazy.
7970 has support on the driver level, but it's not fully optimized in BF4. Not sure if there are no benefits, but it's definitely not running as well as it could be.
Which, in the other hand, also shows the bad side of Mantle: every game have to optimize paths for every card generation in a more specific way than with Dx. Low level api = more job to cover all the video cards.
I have a 7970 and my experiences with mantle was crashing and memory leak :/ I understand it's a beta and it's not optimized. However I did notice a 10+ fps improvement when it did run fine.7970 has support on the driver level, but it's not fully optimized in BF4.

It is my understanding that the current beta drivers are kinda broken when it comes to Crossfire, which might be your issue.
The 7870 supports Mantle correct? It is now rebranded as the 270x as well, right?
Hey you got it running, awesome. I have the same gpu and am having the same issues. I just deactivated it until it gets worked out.
That 780Ti is murdered alright.
No. It's 7790 with the DSP activated ..isn't 260x just a rebranded 7970 with the true audio dsp activated? it should run fine.
I could not get the showgraph command to work but the Drawfps did.Use the perfoverlay showgraph command to confirm. You could be getting much smoother performance without actually seeing a huge framerate improvement.
Mantle turns off AA, lowers the draw distance, and lowers shadow detail.
Something seems weird about those two screenshots you posted.
That or I can see how you gained nearly 35 FPS.
Or it could be dependent on the server you joined and whether the middle building has fallen or not. Not to mention player count on the server.
Not a fair comparison really.

EDIT: You know what, I'm calling that out. Those two shots are fishy. You did something to them Minion or Mantle severely downgrades the game.

Looks like I'm not crazy.
GPU 7950
CPU FX 8-core 8120 (4.0ghz)
The extra fog is noticeable in Siege of Shanghai. I heard the brightness of Mantle is a glitch that will be fixed. The SMAA was a tweak from a program. I posted an updated shot.Strange.. Mantle seems to have lower draw distance or the fog is obscuring the distance with those bf4 screen shots... Can't see the most distant building or the building inbetween the 2. AA also looks to be less active on the power lines ever so slightly?
a little pre and post. i used the test range to try to get the most accurate results.
i5 2500k @ 3.8ghz
amd 7950 @ 925/1250
8 gigs ddr3 1333
everyting ultra, terrain quality/decoration on low (which = ultra), aa deferred off, aa post high, occlusion off
Do you have an intel chip? You have to disable your intel graphics in device manager.

So basically Mantle is only for AMD and low-end Intel CPUs, or for high-end CrossFire setups? In other words, severely CPU-bound PC builds?
People who own an i5 or i7, and a single AMD GPU, need not apply it seems.
Hmm so mantle gave the 280x a 4fps boost over the 770 in BF4. I wonder how behind it was pre mantle because I was expecting like a 20fps jump or something.

I tried to run Star Swarm on my 7870 XT with Mantle, but it crashed to desktop as soon as it started. DirectX worked fine with the 14.1 drivers not that I expected anything different. I assume the Mantle issue was just due to not yet being supported.
They were hyping up some OpenGL commands at Valve's Dev Days, see: http://www.neogaf.com/forum/showthread.php?t=756668What is nVidia doing to match this? ARE they doing anything to match this?

The only thing of record I think is them advocating for Open GL extensions. We know developers want low level access and we know they've spoken out against competing APIs.
Who knows what Nvidia's response will be.
Q. This is just a marketing tool for AMD; youve obviously crippled the DirectX version!
A. We really havent; to be perfectly honest weve spent more time optimizing for DirectX than we have on Mantle. The fact is that DirectX is conceived and implemented as a single-threaded API, and so a lot of the more significant gains we see thanks to the Nitrous engines aggressive multithreading are badly limited by API overhead when were using it.
We obviously cant prove this to the satisfaction of everyone on the Internet, but understand that our primary goal with Nitrous is to make the best engine we can so that we can open the door to the new kinds of games that we want to make (and play ourselves!). An awful lot of the gamers we hope to entertain dont and wont have access to Mantle-enabled hardware any time soon, so wed be making a huge mistake as entertainers and as businesspeople by not supporting or poorly supporting non-Mantle hardware.
From the Oxide FAQ, btw:
They are sorta pushing OpenGL with the newer multi draw command(whose functionality has been apart of Direct X for ages now)but draw calls are only one part of the equation. There are still very prominent issues with things like threading models and end to end register control that can't really be addressed on the level of DX/OGL without complete overhauls.Pushing OpenGL, and probably seeing what happens with DirectX Blue (aka DirectX 12).
I don't think anyone is realistically expecting them to jump on the Mantle train.
The fact that they haven't fully outright denied it tells me that they are at the least considering something, much to the contrary of the resident "experts"Well, for now, their response is simply 'no comment'. We'll have to wait and see.
I actually wonder whether that's all there is to the story. Lacking any concrete information about Mantle API, it's hard to say, but the initial unveil talks gave me the impression this was more than draw-call accelerator, giving you low-level access to aspects like user-controlled memory aliasing (not having your hands tied by the API), which could considerably impact how you implement some things (speed and quality wise).Durante said:Obviously reducing CPU overheads will only improve overall performance as long as overall performance is limited by the CPU. The results follow my pre-release expectations to a T.
