    After last minute hiccups, AMD managed to release Catalyst 14.1 beta to the press. The driver brings along the first release of Mantle, AMD's ambitious 3D graphics API to rival Direct3D and OpenGL. Installing the driver was less than straightforward. We couldn't just install the driver over our Catalyst 13.12 WHQL installation like we normally do. A driver cleanup and reinstalling did the trick. Catalyst 14.1 beta enables the 3D renderer option in Battlefield 4, which lets you choose between DirectX 11.1 and Mantle.

    Our first (subjective) impression, is that we couldn't tell the difference. Our Radeon R9 290 already offered frame-rates well above 60 FPS (1920 x 1080, Ultra, 4x MSAA), on Direct3D, and so we never really stood to gain anything that makes the game more playable than it already was. What could have been interesting, was to see how Mantle makes the lives of R9 270X owners better, who could see frame-rates drop below 60 FPS at our settings. According to a change-log of the driver posted by Guru3D, AMD hasn't optimized Mantle for any of the Graphics CoreNext (GCN) based GPUs other than Radeon R9 290 series, R9 260X, and A-Series "Kaveri" APUs.

    [​IMG] [​IMG] [​IMG] [​IMG]

    We gave Battlefield 4 and the Catalyst 14.1 a quick spin. Our test bed included an AMD FX-8350 chip at stock frequencies, 8 GB of DCh DDR3-1333 memory, an AMD 990FX motherboard (ASUS M5A99FX-PRO R2.0, 2201 BIOS, UEFI mode); Windows 8.1 64-bit, and of course, a Radeon R9 290 (BIOS: 015.042.000.000.003747). The GPU is into high-end territory, but the rest of the bed is still what we'd like to call an "aspirational mainstream" build (one that's penny-pinching but shouldn't bottleneck high-end GPUs). Game settings included 1920 x 1080 pixels resolution, disabled V-Sync, "Ultra" preset, HBAO, and 4x MSAA. We used the "PerfOverlay.FrameFileLogEnable 1" console command to spit out CSV files with frame-times in ms, from which we drew average frame-times (time in ms taken to draw a frame), and derived frames per second. Switching between renderers requires game restarts.

    The screenshots above are not from the testing session. In the first run, we chose the Direct3D renderer. Battlefield 4 takes advantage of DirectX 11.1 (feature-level 11.1) on the R9 290. We employed a 167-second play through the single-player campaign chapter "Fishing in Baku," with a constant save-point, where our heroes are fighting their way through hordes of enemies to reach their extraction point. We obtained an average frame-time of 16.26 ms, which works out to 61.5 fps. For Mantle, we overshot the 167-second mark, and played on for 184 seconds (we quit at the same point in in the game as our Direct3D run). The average frame-time was 14.45 ms, which works out to 69.2 fps. Overall, a 12.5 percent performance uplift. On a side-note, in the screenshots above, which we took merely to show you that the Mantle renderer is active, the game is doing 1280 x 720 pixels, and windowed. This is a CPU-limited scenario. The performance uplift is higher.

    Overall, Mantle is far from being termed vaporware. It works like gangbusters, and we couldn't visually tell the difference in game effects between it and Direct3D. Performance gains are tangible, and if AMD gets it to work like it should on mid-thru-performance segment GPUs such as the R9 270 series and R9 280 series; not to mention HD 7800 series and HD 7900 series, AMD owners could be in for a neat free performance upgrade, heck even lower-mainstream chips like the R7 260X and HD 7790 should turn from being 1080p-capable to 1080p-worthy. Mantle works to reduce the API-level overheads imposed on the rest of the system (the CPU, main memory, etc.), in processing graphics. The more CPU-limited the scenario, the better the performance uplift. AMD tells us that public release of Catalyst 14.1 beta should be posted on the company website shortly.

    Some nice tests here involving a 290X and GTX 780 Ghz using various processors:

    That 780 sure hates being CPU limited, Mantle could do it wonders. :p

    A bit disappointed over the limited GPUs that support Mantle thus far: seems like only GCN 1.1 GPUs are supported. Hopefully support for GCN 1.0 GPUs will soon follow.

    DICE has a driver that gives them similar performance gains on an HD 7970. So a public release with optimizations for other GCN GPUs shouldn't be too far off.

    Oh man, free stuff, so disappointing.

    Q: What hardware is supported with Mantle?
    A: At this time, the following Graphics Core Next-based products are supported:

    • AMD Radeon™ R9 Series graphics
    • AMD Radeon™ R7 Series graphics
    • AMD Radeon™ HD 7000 Series graphics
    • AMD Radeon™ HD 8000 Series graphics
    • 2014 AMD A-Series APUs (“Kaveri”)

    That's one of the reasons I'm a bit confused about it... But I guess the driver doesn't run stably enough on GCN 1.0 GPUs yet for AMD to give it out to the public.
    I'm not complaining about Mantle itself; I'm excited to get it, that's why I can hardly wait to give it a go.

    Ugh, PClab is garbage. They'll show a 780 beating a 290(X) in D3D while every other reviewer shows the 780 being easily surpassed

    This is the same crap that was posted in the anand thread about mantle drivers (people were arguing about multithreaded driver support from AMD and pclab benchmarks were posted for a 780 that owned everything....only for real results to be posted in response showing it to be a little faster than a 7970, which is correct).

    If your system runs the game fine right now, then i wouldn't worry about it. There will be glitches you will encounter. What you should really look forward to is the future games. EA is not pushing Mantle on BF4 for BF4. They are pushing Mantle for their Frostbite engine. It sounds like most of their AAA titles in the future will utilize Frostbite 3. Mantle support for BF4 sounds more like a trial run for them.

    I'm waiting to see how this will affect Tom Clancy's Division. That game already look awesome. If I can get high/ultra settings on my lowly 7850, that would be awesome. I miss the old 8800GTX days where it lasted for years instead of just 1.

    Hmm - I guess I´ll have to ditch my GTX 770 for a R290X.......
    Oh well - lets see some reviews and tests first :ohwell:

    I want to see minimum framerates. Especially some of the maps that have bad drops into the 30's fps(paracel storm at B, Hainan Resort at C are the biggest problem areas) and that is regardless of quality/resolution settings.

    I wonder how mantle affects frame stability other than raw fps, can't wait to see more about this tech

    Idea is not new and has long been known;) !since the beginning of the development and use dual-core processors ! we want to use their full potential .That the engines coming Finally, I will say:rockout:.
    Only the rights are turning the big bucks and stick to another outdated technology they in every way they wish to sell !
    Finally, I will say for a few sentences of software supportwhich is becoming virtually obligatory for emerging technologies !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!:clap:

    Keep calm.....deep breaths....
    PCLabs is using a GTX 780 GHz Edition - usually a stand-in for the 780 Ti where that card isn't available (performance being roughly equal). As you can see, the 1019 base/1072 boost frequencies indicate it isn't your usual run of the mill 780

    Yes, it's clearly a giant conspiracy. You've done well uncovering it.

    I really wish Arma 3 adopt Mantle as it is the most cpu limited game I've played.

    hmm this might help me since I'm still on i7-920.

    Only one big problem - I'm on Nvidia card :cry::cry:

    strange choice of numbers, did you mean 8800gt? but most people with that were on lower resolutions, i cant imagine what they had to deal with at 1080p if a 4850 was faster (& i had a 4870x2 where a lot of games werent hitting 60 on a single 4870 at 1080p/1200p)

    8800gtx was a $600+ high end card, a 7850 is not a $600 high end card, a 7970 would be the right comparison, but both of these 7 series are going strong for 2 years onward

    everything lasts as long as you want it, it's still few games that want to cram a ton of eye candy in them, depending on the resolution you're trying to hit of course

    only big paradigm shifts seem to be the brick walls, like when games started getting very shader heavy (i've seen crysis on a 7900gs, it ran 2fps compared to 20+ on an 8800gt at the same settings), or when dx9b games stopped appearing which blocked x800 & 9800 users

    Basically, the more CPU limited the your setup is, the greater the improvement Mantle will make over DX.

    I'd like to see something like an old Athlon x2 paired with a R9 xxx. Would be interesting.
