If you claim them before September 19th, you can now get all five expansion packs for Battlefield 4 for free. This comes a month before Battlefield 1 launches, and it hopes to get people hooked further into the gameplay style, wanting more in a month's time. They have occasionally been through the “On the House” promotion in the past, on an individual basis, but this is the first time that they're all free, together.
It seems to be...
This will probably upset some Battlefield 4 Premium owners, but, even though I'm one of them, I don't think it's that big of a deal. It's fine for EA to give away their own content whenever they like, and, even still, paying customers bought access to it for over three years before it was given away.
I should note that you need to own the game, itself, though. It currently costs $19.99, although it's recently been available for $5, so hopefully you picked it up by then.

Mantle is currently supported by the Nitrous, Frostbite 3 and CRYENGINE engines, and the current official list of released or soon to be released games that support the new API has reached eight AAA titles. eTeknix lined up three of these games to test, Battlefield 4, Thief and PvZ Garden Warfare to test on an R9 290X paired with both a AMD FX-8350 and an FX-4100. For BF4 with the Ultra preset, no V-Sync @ 1920 x 1080 both systems saw a noticeable jump in performance and Thief even more so for the FX8350 system. Check out the full results in their review.
"The biggest claim to fame of this new low-overhead API is its use in EA’s Battlefield 4 blockbuster and the support it has from EA’s famous FrostBite 3 Engine. However, what is all the fuss about? How does Mantle actually perform in practice? Why should you even care about it? These are questions we are hoping to address today."

BF4 Integrates FCAT Overlay Support
Back in September AMD publicly announced Mantle, a new lower level API meant to offer more performance for gamers and more control for developers fed up with the restrictions of DirectX. Without diving too much into the politics of the release, the fact that Battlefield 4 developer DICE was integrating Mantle into the Frostbite engine for Battlefield was a huge proof point for the technology. Even though the release was a bit later than AMD had promised us, coming at the end of January 2014, one of the biggest PC games on the market today had integrated a proprietary AMD API.
When I did my first performance preview of BF4 with Mantle on February 1st, the results were mixed but we had other issues to deal with. First and foremost, our primary graphics testing methodology, called Frame Rating, wasn't able to be integrated due to the change of API. Instead we were forced to use an in-game frame rate counter built by DICE which worked fine, but didn't give us the fine grain data we really wanted to put the platform to the test. It worked, but we wanted more. Today we are happy to announce we have full support for our Frame Rating and FCAT testing with BF4 running under Mantle.
A History of Frame Rating
In late 2012 and throughout 2013, testing graphics cards became a much more complicated beast. Terms like frame pacing, stutter, jitter and runts were not in the vocabulary of most enthusiasts but became an important part of the story just about one year ago. Though complicated to fully explain, the basics are pretty simple.
Rather than using software on the machine being tested to measure performance, our Frame Rating system uses a combination of local software and external capture hardware. On the local system with the hardware being evaluated we run a small piece of software called an overlay that draws small colored bars on the left hand side of the game screen that change successively with each frame rendered by the game. Using a secondary system, we capture the output from the graphics card directly, intercepting it from the display output, in real-time in an uncompressed form. With that video file captured, we then analyze it frame by frame, measuring the length of each of those colored bars, how long they are on the screen, how consistently they are displayed. This allows us to find the average frame rate but also to find how smoothly the frames are presented, if there are dropped frames and if there are jitter or stutter issues.

Now that the new Mantle enabled driver has been released several sites have had a chance to try out the new API to see what effect it has on Battlefield 4. [H]ard|OCP took a stock XFX R9 290X paired with an i7-3770K and tested both single and multiplayer BF4 performance and the pattern they saw lead them to believe Mantle is more effective at relieving CPU bottlenecks than ones caused by the GPU. The performance increases they saw were greater at lower resolutions than at high resolutions. At The Tech Report another XFX R9 290X was paired with an A10-7850K and an i7-4770K and compared the systems performance in D3D as well as Mantle. To make the tests even more interesting they also tested D3D with a 780Ti, which you should fully examine before deciding which performs the best. Their findings were in line with [H]ard|OCP's and they made the observation that Mantle is going to offer the greatest benefits to lower powered systems, with not a lot to be gained by high end systems with the current version of Mantle. Legit Reviews performed similar tests but also brought the Star Swarm demo into the mix, using an R7 260X for their GPU. You can catch all of our coverage by clicking on the Mantle tag.

A quick look at performance results
Late last week, EA and Dice released the long awaited patch for Battlefield 4 that enables support for the Mantle renderer. This new API technology was introduced by AMD back in September. Unfortunately, AMD wasn't quite ready for its release with their Catalyst 14.1 beta driver. I wrote a short article that previewed the new driver's features, its expected performance with the Mantle version of BF4, and commentary about the current state of Mantle. You should definite read that as a primer before continuing if you haven't yet.
Today, after really just a few short hours with a useable driver, I have only limited results. Still, I know that you, our readers, clamor for ANY information on the topic. I thought I would share what we have thus far.
As I mentioned in the previous story, the Mantle version of Battlefield 4 has the biggest potential to show advantages in times where the game is more CPU limited. AMD calls this the "low hanging fruit" for this early release of Mantle and claim that further optimizations will come, especially for GPU-bound scenarios. Because of that dependency on CPU limitations, that puts some non-standard requirements on our ability to showcase Mantle's performance capabilities.
For example, the level of the game and even the section of that level, in the BF4 single player campaign, can show drastic swings in Mantle's capabilities. Multiplayer matches will also show more consistent CPU utilization (and thus could be improved by Mantle) though testing those levels in a repeatable, semi-scientific method is much more difficult. And, as you'll see in our early results, I even found a couple instances in which the Mantle API version of BF4 ran a smidge slower than the DX11 instance.
For our testing, we compiled two systems that differed in CPU performance in order to simulate the range of processors installed within consumers' PCs. Our standard GPU test bed includes a Core i7-3960X Sandy Bridge-E processor specifically to remove the CPU as a bottleneck and that has been included here today. We added in a system based on the AMD A10-7850K Kaveri APU which presents a more processor-limited (especially per-thread) system, overall, and should help showcase Mantle benefits more easily.
A troubled launch to be sure
AMD has released some important new drivers with drastic feature additions over the past year. Remember back in August of 2013 when Frame Pacing was first revealed? Today’s Catalyst 14.1 beta release will actually complete the goals that AMD set forth upon itself in early 2013 in regards to introducing (nearly) complete Frame Pacing technology integration for non-XDMA GPUs while also adding support for Mantle
and HSA capability.
Frame Pacing Phase 2 and HSA Support
When AMD released the first frame pacing capable beta driver in August of 2013, it added support to existing GCN designs (HD 7000-series and a few older generations) at resolutions of 2560x1600 and below. While that definitely addressed a lot of the market, the fact was that CrossFire users were also amongst the most likely to have Eyefinity (3+ monitors spanned for gaming) or even 4K displays (quickly dropping in price). Neither of those advanced display options were supported with any Catalyst frame pacing technology.
That changes today as Phase 2 of the AMD Frame Pacing feature has finally been implemented for products that do not feature the XDMA technology (found in Hawaii GPUs for example). That includes HD 7000-series GPUs, the R9 280X and 270X cards, as well as older generation products and Dual Graphics hardware combinations such as the new Kaveri APU and R7 250. I have already tested Kaveri and the R7 250 in fact, and you can read about its scaling and experience improvements right here. That means that users of the HD 7970, R9 280X, etc., as well as those of you with HD 7990 dual-GPU cards, will finally be able to utilize the power of both GPUs in your system with 4K displays and Eyefinity configurations!
This is finally fixed!!
As of this writing I haven’t had time to do more testing (other than the Dual Graphics article linked above) to demonstrate the potential benefits of this Phase 2 update, but we’ll be targeting it later in the week. For now, it appears that you’ll be able to get essentially the same performance and pacing capabilities on the Tahiti-based GPUs as you can with Hawaii (R9 290X and R9 290).
Catalyst 14.1 beta is also the first public driver to add support for HSA technology, allowing owners of the new Kaveri APU to take advantage of the appropriately enabled applications like LibreOffice and the handful of Adobe apps. AMD has since let us know that this feature DID NOT make it into the public release of Catalyst 14.1.
The First Mantle Ready Driver (sort of)
A technology that has been in development for more than two years according to AMD, the newly released Catalyst 14.1 beta driver is the first to enable support for the revolutionary new Mantle API for PC gaming. Essentially, Mantle is AMD’s attempt at creating a custom API that will replace DirectX and OpenGL in order to more directly target the GPU hardware in your PC, specifically the AMD-based designs of GCN (Graphics Core Next).
Mantle runs at a lower level than DX or OGL does, able to more directly access the hardware resources of the graphics chips, and with that ability is able to better utilize the hardware in your system, both CPU and GPU. In fact, the primary benefit of Mantle is going to be seen in the form of less API overhead and bottlenecks such as real-time shader compiling and code translation.
If you are interested in the meat of what makes Mantle tick and why it was so interesting to us when it was first announced in September of 2013, you should check out our first deep-dive article written by Josh. In it you’ll get our opinion on why Mantle matters and why it has the potential for drastically changing the way the PC is thought of in the gaming ecosystem.

If you have been following the mess than has been Battlefield 4 since its release, what with the crashing on both PCs and consoles, you know that EA and DICE have decided that fixing the broken game is the number 1 priority. Gee, thanks.
While they work on that though, there is another casualty of development other than the pending DLC packs: AMD's Mantle version of the game. If you remember way back in September of 2013, along with the announcement of AMD's Hawaii GPUs, AMD and DICE promised a version of the BF4 game running on Mantle as a free update in December. If you are counting, that is just 1 more day away from being late.
Today we got this official statement from AMD:
After much consideration, the decision was made to delay the Mantle patch for Battlefield 4. AMD continues to support DICE on the public introduction of Mantle, and we are tremendously excited about the coming release for Battlefield 4! We are now targeting a January release and will have more information to share in the New Year.
Well, it's not a surprise but it sure is a bummer. One of the killer new features for AMD's GPUs was supposed to be the ability to use this new low-level API to enhance performance for PC games. As Josh stated in our initial article on the subject, "It bypasses DirectX (and possibly the hardware abstraction layer) and developers can program very close to the metal with very little overhead from software. This lowers memory and CPU usage, it decreases latency, and because there are fewer “moving parts” AMD claims that they can do 9x the draw calls with Mantle as compared to DirectX. This is a significant boost in overall efficiency."
It seems that buyers of the AMD R9 series of graphics need to wait at least another month to really see what the promise of Mantle is really all about. Will the wait be worth it?

Tagged: battlefield 4, win 8.1
One of the more interesting results from [H]ard|OCP's testing with Battlefield 4 was the RAM usage they observed, cards with 3GB or more of VRAM used 2.25GB of RAM at most points, cards with less topped out at 1.75GB of usage. This proved that some of the performance anomalies they saw from NVIDIA cards was not necessarily a VRAM issue. The R9 290X took top spot but even the 270X and GTX760 could manage Ultra settings at 1080p so almost anyone with a modern card should be able to enjoy all of the eye candy in BF4. Check out the exact results in their full review.
"Battlefield 4 is this holiday season's blockbuster from the Battlefield series. It features the brand new Frostbite 3 game engine which provides a higher level of realism in the game. We strap 8 video cards to the test bench to see what kind of gameplay experience is delivered under Windows 8.1."
