    I have a WDDM1.2 and WDDM2.0 setup working in tandem right now, and it seems to be working OK with DXdiag reporting DX12 support.

    Intel HD3000 + Radeon HD7970 Ghz with hardware Lucid Virtu support on my motherboard.

    Mixed mode will work with heterogeneous GPUs. However you can't do mixed mode when both GPUs are from the same vendor, because you only have one driver instead of two.
  • yannigr2 - Wednesday, July 29, 2015 - link

    Thanks for the clarification.
    I am using an HD7850 and an GT 620 Fermi based and I was about to write a comment like blaktron's before reading your post.
  • blaktron - Wednesday, July 29, 2015 - link

    Sorry, wasn't challenging your article, its just made clear in the Nvidia blog post and wanted to reassure other Optimus/lucid/whatever users. It did take a little work to get the Catalyst 15.7 drivers installed instead of the 200/7900 series windows update drivers though.

    Ryan;

    DX12 Benchmark for Ashes of the Singularity are coming out this week.

    "Ashes will give you a real preview of DirectX 11 vs. DirectX 12 in terms of real world performance. What matters in particular is that Ashes is being optimized for both DirectX 11 and 12. We need it to run extremely well on DirectX 11. You can also compare it to Mantle which will give you a preview of how it will run on Vulkan in the future.

    DirectX 12 Benchmark Release Schedule: [UPDATE]

    •Officially released to the media: August 13

    •Released to the Founders: August 20"

    Why are radeon 4800, 5800, and 6800 series not even in that table? There are thousands of perfectly good 6850s out there that can play modern games....
  • jeffkibuule - Wednesday, July 29, 2015 - link

    They don't support DirectX 12? Did you read the article?
  • Mr Perfect - Wednesday, July 29, 2015 - link

    AMD announced a while back that anything pre-GCN isn't receiving X12 support. A little annoying, but my 6870 is getting more then a little stressed these days.
  • StevoLincolnite - Wednesday, August 5, 2015 - link

    I am running triple Radeon 6950 2Gb cards unlocked into 6970's. They still have ample punch, I don't think I have had an unplayable game yet at 1080P.

    The main benefit that Direct X 12 brings though is performance... Which ironically is what older systems will need the most.

    Still, I'm going to wait for AMD's next lot of GPU's before I upgrade my 6000 series cards, by then we might have the software to take advantage of the hardware.
  • AndrewJacksonZA - Wednesday, July 29, 2015 - link

    My 6670 runs perfectly fine on Windows 10. However, this list is for DX12 GPUs.
  • Gigaplex - Wednesday, July 29, 2015 - link

    4800? I didn't think they worked on 8.1 either. AMD dropped support for that series.
  • jimbo2779 - Thursday, July 30, 2015 - link

    I have a 4890 working just fine in 8.1, why would it not work?
  • Gigaplex - Monday, August 3, 2015 - link

    Because AMD dropped support for the 4000 series before they updated their driver installer to support Windows 8.1. Catalyst 13.1 was the last driver to support the 4000 series, and it doesn't install on Windows 8.1. I suspect you did an in-place upgrade from 8 to 8.1, which worked around the driver installer issue.
  • S1ntti - Monday, August 3, 2015 - link

    Those cards happen to be 7-4 years old
  • makerofthegames - Wednesday, July 29, 2015 - link

    What's the status of TeraScale GPUs? My desktop rocks a 6870, and I was planning to use that as my test platform before putting it on my laptop.
  • makerofthegames - Wednesday, July 29, 2015 - link

    I'm aware they won't have DX12 support, but is there otherwise solid driver support?
  • AndrewJacksonZA - Wednesday, July 29, 2015 - link

    As stated above, my 6670 runs perfectly fine on Windows 10.
  • blaktron - Wednesday, July 29, 2015 - link

    Just not in WDDM2 mode or with DX12
  • makerofthegames - Wednesday, July 29, 2015 - link

    Does WDDM2 offer anything of value besides DX12 support? I see some efficiency improvements, but they require hardware features I'm not sure VLIW5 has.

    Is there any point in having WDDM2 drivers for VLIW5/4, besides the compatibility issues with heterogeneous multi-GPU setups? If so, does anyone know if AMD is planning to make them?
  • Cryio - Thursday, July 30, 2015 - link

    WDDM1.2 in W8 and WDDM1.3 in W8.1, at first glance, offer increased smoothness in desktop operation compared to Windows Vista's WDDM 1.0 and W7's 1.1.

    Other than that, newer WDDM offer lower resource usage, better error handling, therefore fewer Blue Screen of Deaths AND it's what basically offers proper hardware acceleration in browsers, media players like Media Player Classic or VLC.

    HD 2000-3000-4000 offers WDDM 1.1 support, so basically Windows 7 level of hardware acceleration and driver model efficiency. HD 5000-6000 offers support for WDDM 1.3 in Windows 8.1, but apparently AMD won't offer them support for WDDM 2.0 for various reasons.

    Point is, any WDDM 1.x GPU driver should work just fine in Windows 10. So even ATI's Pixel Shader 2 GPUs should work just fine on Windows 10.
  • siriq - Thursday, July 30, 2015 - link

    Won't be any plan from AMD to support DX 12 to 5xxx or 6xxx series cards.
  • MrCommunistGen - Wednesday, July 29, 2015 - link

    Like the Fermi cards mentioned in the article, cards that have WDDM 1.3 drivers will continue to use those drivers in Windows 10.
  • tipoo - Wednesday, July 29, 2015 - link

    No DX12 support, but they'll work fine otherwise in 10, just like they do in 8.1
  • postembr2 - Wednesday, July 29, 2015 - link

    Im still deeply concern about game compatibility within Windows 10.
    Several games had troubling issues, with BF4 constant crashes, and Total war, while worked, always crashed on end turn, regardless of visual settings or shader engine; it suggests more things changed within Windows internal memory or library management that is causing issues.
  • Achaios - Wednesday, July 29, 2015 - link

    Only n00bs and fanbois will rush to install Windows 10 today. Tech savvy ppl will do so after 6 months, so that M$ have got time to iron out all the inevitable bugs.
  • BMNify - Wednesday, July 29, 2015 - link

    Using language like M$ makes you a n00b not tech savvy as you imagine yourself.
  • Notmyusualid - Wednesday, July 29, 2015 - link

    ^^ This.

    I have it only on my spare machine. My main rigs - not yet, no way. And for the gaming one, maybe I'll wait out the whole 12 months.

    Depends on what DX12 stuff I'm missing, I guess...
  • Gigaplex - Wednesday, July 29, 2015 - link

    Some tech savvy people like myself are software developers. The software won't be fixed if we don't get in there early and fix it. We're not all n00bs and fanbois.
  • warmon6 - Thursday, July 30, 2015 - link

    Well... You must of proved yourself as not being much in the way of "tech savvy".

    REAL tech savy people that have the time and patience for this (not everyone will have the time to do this), will be either running VM's or Running it on a spare system to verify what works for them, what doesn't, what still is rough around the edges, and report back to hopefully fix these issues.

    Also, tech savy people need to get into a new OS to figure out the in and outs of it. As guess what, without tech savy people, those non-tech savvy people will have no one to turn to when a problem does arise.

    and lastly what has already been pointed out, Not all tech savvy people are just people that builds systems for themselves. They also include hardware engineers and software programmers. If they followed what you said, we would still be on windows ME (shutters).
  • piiman - Saturday, August 1, 2015 - link

    "Tech savvy ppl will do so after 6 months,"
    Tech savvy people would have been running the Insider preview for many months by now, guess you aren't as tech savvy as you think.
  • HighTech4US - Wednesday, July 29, 2015 - link

    Ryan when can we expect a report of DX12 performance on these GPUs?
  • Ryan Smith - Wednesday, July 29, 2015 - link

    Once there are retail DX12 games to test.
  • HighTech4US - Wednesday, July 29, 2015 - link

    How about running some of the available DX12 synthetic tests before then?
  • tuxfool - Wednesday, July 29, 2015 - link

    I think it would be interesting. One could possibly gauge driver development as more games start appearing.
  • Cryio - Thursday, July 30, 2015 - link

    Synthetic tests were testing driver and CPU performance, so testing GPUs for DX12 using 3DMark's test is useless.
  • Despoiler - Wednesday, July 29, 2015 - link

    Ashes of the Singularity will have their DX12 benchmark available to the press on August 13th.

    http://www.littletinyfrogs.com/article/469403/Ashe...
  • mateau - Wednesday, August 12, 2015 - link

    Ryan;

    You have Starswarm. And you have 3dMark API Overhead Feature Test. Why not run those benchmarks?

    API Overhead is a test that highlights AMD Asynchronous Shader Pipelines and Compute Engines.

    Why not run what you have available?

    Consumers read your reports to try an make an educated choice about buying graphics APUs and dGPUs.

    You can not render what you have not drawn. 3dMark is extremely relevant.
  • azazel1024 - Wednesday, July 29, 2015 - link

    I suppose the answer is no, but out of curiosity, any ability or plans to support Ivy? Also what about the state of Atom support? IIRC Braswell/Cherry Trail carries Gen 8 graphics, so I'd imagine DirectX 12 COULD support it, but will it/does it? What about older Bay Trail? I assume no/won't.
  • looper - Wednesday, July 29, 2015 - link

    Win10 gets DL'd to one's PC, but not installed, correct? This PC is for gaming primarily, and we love Win 7's stability with Battlefield 4, and I'm concerned that Win 10 will have issues....
  • HighTech4US - Wednesday, July 29, 2015 - link

    It does have issues, some are even critical

    http://techreport.com/news/28714/windows-10-arrive...
  • Andrew LB - Saturday, August 1, 2015 - link

    The vast majority of problems i've seen people have are user error. Some common issues are trying to upgrade with incorrect drivers installed, or while overclocked, and things never install right if your PC has a virus/malware that your antivirus software doesn't detect.

    - Before moving to Windows 10, one should always run multiple stand-alone virus/malware scanners like TDSSKiller, Stinger, HijackThis, etc. And don't even think about using ComboFix unless you REALLY know what you're doing. That program will FUBAR your PC faster in an instant.
    - Also, if you have any software that is windows version specific like for example "windows 7 manager"... uninstall it before upgrading.
    - Reset your BIOS to default performance settings if you're overclocking.
    - Restore default clock speeds on any graphics cards if overclocked
    - Re-enable all disabled Windows Services (click start > Run > type "services.msc") Don't do it through msconfig.exe
    - Disable any programs that have an overlay or OSD
    - If you have tons of devices plugged into your PC, unplug them

    I made the upgrade to Win 10 Pro today and didn't have a single problem because I followed these guidelines. And considering how much stuff I have in my PC, I'm guessing my setup would be at higher than normal risk of an issue. SLI GTX 780ti, X-Fi Titanium HD, 1xSSD, 2x Raid-0 pairs (4 drives), dual displays, 5 partitions, 1x external 1tb ESATA, laser printer, scanner, tablet, etc.
  • piiman - Saturday, August 1, 2015 - link

    "I made the upgrade to Win 10 Pro today and didn't have a single problem because I followed these guidelines."

    Also upgraded without a single problem and I didn't follow a single item on your list. You wasted a ton of time :-)
  • Impulses - Wednesday, July 29, 2015 - link

    You can download install media at any time here:

    https://www.microsoft.com/en-gb/software-download/...

    I'm still unsure how the process of upgrading keys is best carried out tho (specially in my case where I have a bunch of Win 7 academic keys and I'd like upgrade them all, might have to play around in a VM).

    AFAIK once you actually upgrade you can't go back and activate the old OS with the same key tho, since it'll now be a 10 key... You got a year, waiting a bit won't hurt anything.
  • hulu - Wednesday, July 29, 2015 - link

    Actually you have one month to revert back to Windows 7/8. If you don't do it by then, you're stuck with Windows 10.
  • toyotabedzrock - Wednesday, July 29, 2015 - link

    Revert? I think he is talking about waiting to upgrade.
  • Impulses - Wednesday, July 29, 2015 - link

    He was probably referring to my reply where I mentioned that you can't go back, but you can always wait up to a year.
  • YukaKun - Wednesday, July 29, 2015 - link

    What about notebook re-brands?

    Should I guide my upgrade decision by code name or OEM branding? Case in point: I have a GTX675M (GTX580M) in my lappy.

    Cheers!
  • olafgarten - Wednesday, July 29, 2015 - link

    As your chip is Fermi, it won't support DX12, but if it works in 8.1, it will work in 10.
  • HighTech4US - Wednesday, July 29, 2015 - link

    GeForce Windows 10 Driver 353.62 - WHQL Released Today :

    http://www.geforce.com/drivers/results/87789

    Clearly shows that Fermi are supported on DX12
  • Ryan Smith - Thursday, July 30, 2015 - link

    If you check the driver, you should find that Fermi cards are using a WDDM 1.3 path.
  • HighTech4US - Thursday, July 30, 2015 - link

    Where/How can I check a driver for that?

    Looking on the linked page I cannot see the usual Notes section.

    Do you need to install the driver first to find out?
  • Ryan Smith - Thursday, July 30, 2015 - link

    DXDIAG can tell you.
  • YukaKun - Saturday, August 1, 2015 - link

    Thanks for the answers!

    Cheers!
  • siriq - Thursday, July 30, 2015 - link

    Don't support DX 12 yet but will support Dx 12 soon. That is unfortunate Fermi driver is not ready yet for New directx. Let's hope, next month or so will be fixed.
  • toyotabedzrock - Wednesday, July 29, 2015 - link

    This is why constantly relabeled mobile gpus are a huge problem. There is a large number of recent laptops that shipped with 820m dedicated gpus and they where still shipping them recently!
  • Notmyusualid - Wednesday, July 29, 2015 - link

    I got caught once with the re-branding madness. Still upset to this day....
  • babadivad - Wednesday, July 29, 2015 - link

    What about mobile GPUs?
  • dgmballa - Wednesday, July 29, 2015 - link

    that's disappointing, I have 3 gtx 580 1.5 gig fermis. I was hoping I could finally stack memory on these 3 cards for more performance, I hope this gets fixed soon!
  • HighTech4US - Wednesday, July 29, 2015 - link

    DX12 Driver for Fermi is here: http://www.geforce.com/drivers/results/87789
  • Gigaplex - Thursday, July 30, 2015 - link

    That driver does not support DX12 on Fermi.
  • kn00tcn - Friday, July 31, 2015 - link

    excuse me? you first need a dx12 game AND you need the dev of the game to decide to support stacked memory... of course, memory size doesnt mean performance either
  • mikep012 - Thursday, July 30, 2015 - link

    Will the Radeon HD 8210 be upgraded as well? I'm looking to get a new one, though.
  • xxgaboxxhb - Thursday, July 30, 2015 - link

    hi i have a GPU nvidia gt630 and the problem is that win 10 doesn`t detect my GPU

    i already install the new drivers but still doesn`t detect and i cant open nvidia control panel

    i just can open geforce experience plz help :)
  • Sick as - Friday, July 31, 2015 - link

    I have a GTX 960 and am having real problems trying to load drivers that actually install. Nvidia drivers just say failed, windows drivers cause multicoloured stripes all over the screen. Why did I upgrade........
  • akamateau - Friday, July 31, 2015 - link

    @Ryan Smith

    Ryan;

    When is AnandTech going to continue the Starswarm and 3dMark API Overhead Feature tests this time on AMD's Fury series dGPU cards and new A series APU's?

    Now that DX12 and new GPU's are in the market consumers need to make educated buying choices.
  • nuchamber - Friday, July 31, 2015 - link

    will my geforce 7800 gtx windows 7 64bit be supported ?
  • lifeware04 - Saturday, August 1, 2015 - link

    I am looking over the internet for any test with the multi gpu set up with directx12.

    can someone point me to it because I am planning to upgrade my system with new GPUs.
  • SeanJ76 - Thursday, August 27, 2015 - link

    No SLI support still??
    /sigh I guess I'll keep Windows 7 for a while longer!
