BF4's Mantle Patch Out But Wait for Necessary AMD Drivers

[azzazel_99]

Hahah show me a mid level or even high level amd card that beats the 780ti? Oh wait there isnt lol. They may come close but they dont match or beat it without some heavy overclocking or mods. No mid level amd card will be on par with nvidia. You pay a premium being with nvidia but thats a premium im willing to pay for better cards, drivers and performance. The onky good thing about amd is they help keep nvidia prices somewhat competitive. The 290x flagship card from nvidia was a terrible fail compared to the hype it got pre launch and the 290 being the price it is makes it a pointless buy. Mantle is not going to make a 270x or 280x run like a 780ti....sorry it aint gonna happen. Oh and show me a 780ti that puts out more heat, noise and uses more power than any new amd card. The 280x 290 and 290x all put out more heat, use more power and are WAYYYYYYYYY noisier than any new nvidia card.

Let's hope so because if only three cards are initially supported then your post is going to look a bit daft isn't it?

Even if BF4 doesn't (unlikely), most guesses made here about which cards aren't supported do not have much merit behind them, for instance:

Most of the comments complaining about this that I've read, say something along the lines of it only supporting GCN 1.1, or that its the 200 series only, not 7000. If, (once again, pointing back to the article you should have read), you clicked the link showing the benchmarks DICE have run so far, you'd see the middle benchmark is done on a 7970, a GCN 1.0 card. Architecturally there is no difference between this card, and any of the GCN 1.0 cards in the 7000 series (which are also the same as the GCN 1.0 cards in the 200 series). As AMD has stated before, Mantle currently will only support GCN. This means most 7000 series cards, and all 200 series cards. This has also been confirmed by the AMDRadeon twitter account.

It feels very intentionally misleading that their test case is an A10-7850K with an R9 290X.This platform would be insanely CPU-limited, which is why it sees such a large boost.Most people will have a more balanced build, or even one where the system bottleneck lies with the GPU, and would see far less of an improvement.Mantle is a Good Thing, but don't tell people to expect what they won't get :/

I don't see a problem with this. If you are building a gaming PC from scratch, you won't see much gains. But many people buy graphics cards to upgrade an existing PC, maybe their parents bought them or a family PC or something. It's usually processor limited, so all they have to do is buy a graphics card to play the latest PC games, and seeing a 50% better performance from one card over another for certain games certainly helps in the decision of which one to buy.This is like 3DFX voodoo vs direct3D all over again. I remember playing the original grand theft auto with both drivers. The heavily optimized 3dfx voodoo was simply awsome, huge performance gains over direct3d. But ultimately the proprietary nature of 3DFX voodoo lost out to the universal nature of Direct3D.

But Glide worked on all 3DFX cards and their derivatives whilst Mantle only works on a select few GCN 1.1 cards and one APU at the moment.

Mantle hasn't even been released yet. It's still at the beginning stages, and obviously AMD invested time and effort into designing an architecture to give them a edge over nvidia. I'm sure all of their future graphics offerings, including their integrated graphics will be using this architecture. It would really give AMD an edge over Nvidia for people with computers that don't have the extra coin to buy a new motherboard+CPU+RAM, and simply want more frame rates however they can get it.

Actually it has been released and requires a 1.2GB downloaded patch, it's the driver that hasn't been released.

Regardless that's besides the point. You can't use it yet and you're already criticizing that it's not available on their entire product lineup???? You do realize that some of AMD's and Nvidia's GPU's are actually tweaked versions of their past generation's higher tier lineup. They tend to name GPU's based on a performance capability scale rather than the internal architecture.

Yeah, the improvement with a decent CPU like the I5 or I7 is only like 2-3%. It's purely for their slow CPU/APUs. Even when the new Catalyst is released, it'll only be for the new GPUs - R8, R9 etc, they've intentionally left out 79xx, 78xx despite them being identical to R8, R7 and using GCN to trick people into upgrading.

Apparently neither of you read the performance numbers. An A10 with no discrete GPU showed a smaller performance gain than an i7 with a couple of R9-290s in crossfire. The setups they used were balanced although there weren't any midrange machines. Granted the numbers aren't trustworthy until see some more independent testing, but I'm amazed how many AMD/Intel/Apple/Android... basher's will jump on someones retarded comment just because it supports their point of view. Until there are some more real results all we can see is that it seems mantle gives a considerable performance boost.

http://battlelog.battlefield.com/bf4/news/view/bf4-mantle-live/ if you look at those charts on the performance section it clearly shows that the more CPU & GPU you give the Mantle setups the bigger the gains you get from it I mean it shows a Intel i7 3970x with radeon 290x gaining up to 58% with mantle so not sure where some of got the idea that they were only showing low end cpu/gpu combos gaining anything. thx

I think a lot of you guys aren't taking into consideration the system specs in relation to the resolution in each benchmark scenario, because that can have a big impact on creating a CPU bound situation even with an i7-3960X. I'm inclined to agree with Hilbert Hagedoorn's assessment over at Guru3D. It seems like DICE designed the benchmarks to create CPU bound situations, especially in the highest-end configuration, playing off of Mantles strengths and making the results look as good as possible in comparison to DX11. I mean, does anyone else think running a system with a 3960X and xfire 290X on a 1080p monitor is kind of absurd? Overall I think the results are a little unrealistic, and probably represent the upper end of what can be achieved with Mantle, as opposed to a real world representation of what to expect on a balanced system.http://www.guru3d.com/news_story/dice_releases_battlefield_4_directx_vs_mantle_performance_numbers.html

I know people running this kind of setup. You currently can't get high refresh rates, like 144hz (which many gamers prefer over large resolutions), on resolutions higher than 1080p, so this setup is still viable.

I've been critical of that since the announcement of Mantle and you don't seem to realise how long I've been around because if you did you wouldn't have the cheek to post such nonsense.

you do know the 290x was aimed at the 780 and not the 780ti, also the 780ti is over $700 i paid less for both my 7970s and It will still beat it.

who cares about heat, noise and power consumption. my cards dont go over 75c in crossfire. also you are mostly referencing the reference design cards which are wayyyy louder and dont cool as effectively.

whatever side you choose it doesnt matter, ive run both cards before

must be a nvidia fan boy.....

 

[azzazel_99]

No I just buy whoever makes the best quality and reliable parts at the time and lately its been nvidia in the gpu side. The 290 was aimed at the 780 and the 290x was aimed to be too dog flagship and be the beat all nvidia products from amd. They just didnt expect nvidia to retaliate with a card that ate it for lunch. Everyone cares about heat noise and power consumption. Noone wants a blow drier in their pc's which is why so many people complai ed about it. Noone wants to have to buy a huge psu just to power a card....Noone wants to have to buy a new case or seriously mod the one they have for better airflow just to support a gpu. All those things are issues with the new amd products. Amd just cant keep up which is why they dropped out of the race against Intel to create the best cpu. Its only a matter of time before they do the same with gpu's. I dont hate them for making decent gpu's it keeps prices at least a little under control with other manufacturers and gives other enthusiasts options who maybe on budgets. But at some point enough has to be enough with driver problems, poor designs and software. Their "fix" for the ref 290 and 290x throttling was a "update" that just turned the fan speed up which anyone using afterburner or any other software could do themselves. They had more than enough time to have their drivers ready for mantle release considering it was supposed to be back in december. This is starting to look more like dice pushed it back for amd or amd asked dice to push it back and blame it on issues with bf4 so amd could play catch up as usual. Again im not a fanboy I just want the best products in my pc regardless of price and amd just doesnt cut it for that category for me.

 

[Mousemonkey]

If DICE had been ready in December and released the patch would AMD have been ready with the driver? I'm guessing no.

 

[azzazel_99]

Exactly my point.

 

[Mousemonkey]

So the next question should be, who is really responsible for the delays? 😗

I'm sure the build is perfectly viable, and I'm glad to hear that the one or two people (hopefully) you know of who do this will see a significant performance boost from Mantle. But that doesn't change the fact that it's a CPU bound situation, and in my opinion an extremely inefficient use of system resources and money.

If this really is the sort of situation where we'll see the biggest gains from Mantle, then I really have to question the point. It would have a far smaller impact on the user base, and an ultra high-end build like that would already achieve more than playable frame rates in DX11 at 1080p. I think it would've been more beneficial for DICE to demonstrate big performance gains in a CPU bound low-end build, where Mantle could make the difference between non-playable and playable frame rates. I think it's far more likely an enthusiast would be in such a situation on the low-end or mid-range, then the scenario you're defending. I mean, wasn't that sort of the main value proposition of Mantle when it was first announced?

That's funny considering I bought a GTX 770 in early November for BF4 and it ran like crap in graphic intensive playing on multiplayer maps. Hardocp verified this in their testing http://is.gd/PzhEZZ and was exactly my experience. It's even funnier reading the forum comments of 770 owners claiming they get 70 FPS average in BF4 at max settings.

I have 2 of them sli and its silky smooth on my benq XL @ 144hz using mix of high and ultra (no msaa, settings optimized for spotting in MP). Silky smooth as in over 144fps. Maybe it's your build. Consider that?

Umm, no. i7 4770k, Z87 Pro, 16gb ram, 256gb Samsung Pro SSD (not that that matters). As I said, Hardocp replicated exactly what I was experiencing with the 770 in early November. I didn't wait around for them to fix it. You damn well better get silky smooth playing, but of course you have no videos to prove a minimum FPS of 144 on maxed settings, msaa off or otherwise. There are multitudes of posters that exaggerate the performance of their machines. I'm saying there is no way for a 770 to average 70-80 FPS on all maps in BF4. Also, if you have Terrain Decorations set on Ultra, it is likely actually Low. Google it.

 

[tinmann]

One of the largest limitations right now is GPU support on AMD’s side. The 14.1 drivers won’t support Mantle on older GCN cards like the HD 7000 / HD 8000 series, the R9 280X and R9 270X. In addition, AMD has warned that multi GPU configurations may experience intermittent stuttering. It gets better and better, now it's only some GCN that will benefit.http://www.hardwarecanucks.com/forum/hardware-canucks-reviews/65244-catalyst-14-1-amd-unleashes-mantle.html

All GCN cards will support Mantle immediately out the door:https://twitter.com/AMDRadeon/status/429291474958565378

The driver itself might but what about Mantle support in BF4?

@Mia_crazymike Yes, AMD Catalyst 14.1 Beta will support ALL desktop GCN products.

That isn't actually mentioned is it?

The Mantle API is supported by all GCN cards. If you want to play a DX11.1 video game, if your card supports it and so does your driver/OS, then it will run in DX11.1 mode. Same goes for Mantle. If your card supports it, and so does your driver/OS, then if you tell a Mantle supported game to run using the Mantle render path, then it will run using Mantle.

That's a really good question because mantle is supposed to replace Direct X but so far only one game supports it and that's Battlefield 4.

 

[azzazel_99]

Haha I have multiple people in my "clan" in bf4 running the 770's and I know for a fact they are averaging 70+ fps with the 2gb models from evga with everything maxxed at 1920x1080. Think what you want but I've seen it. Lol the 760 is a diff story but the 770 is VERY capable.

Anandtech just published a performance preview of Mantle:

http://www.anandtech.com/show/7728/battlefield-4-mantle-preview

There's a lot to digest, but it looks like in GPU bound situations you can expect a 7-10% performance boost over DX11 at 1080p. Even in the most CPU bound scenarios they could manage, dropping a 4960X down to 2C 4T at 3GHz and 4C 8T at 2GHz running low quality settings, the largest performance boost they recorded was ~28%.

Anandtech probably has the highest degree of journalistic integrity of any tech site I read, but I'd probably be suspicious of a site with an AMD sponsored section too, if I weren't so familiar with the site and the authors.

Guru3D also published a preview article and managed an extremely CPU bound situation with an A10-7850K and 290X running medium quality:

http://www.guru3d.com/articles_pages/amd_mantle_preview,1.html

I'd be interested to see how much of the GPU performance can be recovered in such a CPU bound situation using Mantle, compared to a GPU bound situation using the same card in DX11. But overall every scenario I've seen so far with significant performance gains over DX11 seems very contrived and unrealistic. Performance gains in every balanced, and admittedly far more likely scenario I've seen so far seem to hover closer to ~10%. I think if nothing else these performance previews should re-frame peoples expectations.

 

[Mousemonkey]

This might be cherry picked but it still shows that a powerful card is a powerful card regardless of Mantle :-

But for those who have a weak CPU and a powerful card then Mantle will help them out, why anyone would match a powerful card with a weak CPU is a question that many are asking though.

 

[leeb2013]

just installed and.......they've screwed it up. I load BF4, select option, click on graphic and......gone. BF4 shuts down instantly, no warning, nothing.

So back to the 13.12 driver, which they screwed up also as it thinks it's 13.11 and BF4 now wants 13.12 otherwise it complains at the start, meaning I often lose my slot on the server. Absolute freakin' retards.

I had one bad experience with an AMD GPU many years ago and had Nvidia since, with no issues. I thought I'd give AMD a try as they are "better value". I can see why, never again. Back to Nvidia as soon as Maxwell's out.

...fortunately, lots of other people had the same issue (BF4 crashes when going into Options-graphics) and yet again the internet community solved the issue;

http://www.reddit.com/r/battlefield_4/comments/1wrz3o/official_141_beta_driver_download_and_impressions/

You have to disable the integrated GPU on Intel CPUs. Of course AMD would never have tested this.

unfortunately with an I5-3570k and 2x 7950, it makes no difference to CPU or GPU usage. If Mantle is an optimized API for GCN, then why would it only offer an increase in performance to some combinations of weak APU/CPU/GPU? Surely if it works, it works and gains would be seen for all GCN.

Hence my suspicion that AMD (mantle) sponsored games like BF4 are artificially and unnecessarily crippled to be CPU resource hungry and mantle magically removes that crippling for selective weak AMD CPUs.

You have to disable the integrated GPU on Intel CPUs. Of course AMD would never have tested this.

unfortunately with an I5-3570k and 2x 7950, it makes no difference to CPU or GPU usage. If Mantle is an optimized API for GCN, then why would it only offer an increase in performance to some combinations of weak APU/CPU/GPU? Surely if it works, it works and gains would be seen for all GCN.

Hence my suspicion that AMD (mantle) sponsored games like BF4 are artificially and unnecessarily crippled to be CPU resource hungry and mantle magically removes that crippling for selective weak AMD CPUs.

Strange that, someone is saying similar about the Swarm demo.
