    I remember seeing a slide not to long ago that indicates Maxwell is DX12 (tier 2 which was upgraded from tier 1) and all GCN supports DX12 tier 3 (hardware) most likely due to the optimisations from Mantle having close ties with DX12. Intel Iris iGPU supports DX12 tier 2

    You sure, i am positive i was dropping DVD into Windows XP and Windows 7 and they play right away, i could have sworn window players played DVDs by default.

    But i could be wrong, its been a while since a played a DVD on the PC.

    780ti is a great card, it'll last easily (hardware willing of course)

    There's no "DX12 Tier 3", some features have tiers, but not DX12.
    Maxwell Gen 2 is DX12, FL12_1 and Resource Binding Tier 2. Conservative Rasterization Tier is probably 1, Tiled Resources Tier is probably 2 and Typed UAV Tier is probably 1. Rest of feature x tiers is unknown for Maxwell Gen 2.
    Also, make sure you separate Maxwell Gen 1 and Gen 2 when you talk about Maxwells, they have radically different feature sets.

    GCN's are DX12, unknown FL (it's either 11_1 or 12_0, and it could be GCN1.0 = 11_1, GCN 1.1/1.2 = 12_0) and Resource Binding Tier 3. Rest of feature x tiers is unknown at the moment.
    For GCN 1.1 and 1.2 Tiled Resources Tier should be 2 (like it's in DX11.1) and Typed UAV Tier should be at minimum Tier 1 since they've been ahead of NVIDIA on UAV support (as seen from DX11.1/FL11_1)
    For GCN 1.3 / Fiji it should be DX12, FL 12_1 and all feature tiers at max

    I think XP gained that with Media Center edition later on.
    Vista and 7 included Media Center and thus DVD support
    Win 8 had Media Center as add-on which you could purchase (though it was free for limited time offer)

    Even if the OS kernel changes were not a critical showstopper, Microsoft had to pull the plug on backporting WDDM 1.2 to Windows 7 for quite silly reasons like 3rd-party notebook drivers going ballistic with the Direct3D 11.1 runtime querying for new capabilities...

    DXGI/WDDM was engineered to be independent of the OS kernel to a large extent. The problem has much more to do with testing, support and software compatibility in general.

    I guess Microsoft learned it the hard way: it's too much hassle to backport isolated OS components to previous versions when you can't really update other components which you rely upon for the best performance. You get an unsupportable soup of different components that might or might not work together. Doing a full "service pack" type update or a full OS upgrade is a much preferred way to introduce such significant changes.


    Direct3D 11.3 requires WDDM 2.0, so it's Windows 10 only. If Microsoft are essentially retiring Windows 7/8.x with their free Windows 10 upgrade offer, why would they bother to make significant updates to Window 8.x anymore?

    2 new instructions underlined in quote,. Nothing major though, ok except Maxwell voxel GI since its software by GK1xx and GF1xx.

    " yes that is GeForce series 400 and above."

    Whaaaat? My little old 470 will work with DX12 ? :wanker:

    That's awesome news. I'm building a haswell system right now and cant really afford a new card until this fall.

    you are just plain dumb if microsoft was put the people first they let you have dx 12 on windows 7 windows 8 and 10 are full of apps and crap thats why 8 never sold well i would prefer to keep windows 7 but i moved to pc from console gaming coz of the better graphics and performance so dx 12 i want it especially if the sli benefits are as good as there saying so having direct x 12 on windows 10 is basically a way to force u to switch to it from win 7 even if u dont want too

    I can see it now, M$ is to become like EA. Win 10 will be like a BF game. You'll get the main OS for free(upgrade) but then when new features come out M$ will give you the option to buy it for a few $.

    All of a sudden there will be many "new features" for the people to pick from.

    Hilberts not wrong in his assessment about M$ and money. They are being very slippery atm with details on how they will be making money. That worries me. Never once have they explained how this business model is going to work.

    While looking forward to DX12, I too have some concerns about Windows 10, but we'll see how that works out. If they get the gaming boost right, I might close my eyes on other possible issues.

    You just explained how it could work. The other way is how google operates with Android.

    I guess my question is here is what does everyone expect? Microsoft to just continue the course while all these other players just eat up their marketshare? More and more of my friends/family aren't even buying PC's anymore. They just using iPads and phones to do 99.9% of their daily computing stuff.

    Google and Apple just keep chipping away. Microsoft needs to innovate or they die, just like Blackberry.

    I am most interested in in how this all ends up. and probably only reason i care about win10 atm considering what i been hearing about last few tech builds

    There is the issue of Windows 10 making Secure Boot mandatory thus locking out any other OS's like Linux etc although this can still be disabled on most desktop systems it will still affect a lot of laptop users, not really an issue for me as I don't dual boot but it's something to note.

    there is always some drawback.

    I dont dual boot and even if i did it would probably some OS of windows, simply cause if i want to game on pc I really have no choice.

    I would to see what DX12 HW the 2 release, spec wise

    Advantages for dx11 games

    I'm wondering if there will be any advantages with the new API for games already released like Metro and crysis series? Or only with new DX12 ready games? And, what optimized game performance will there be when using Windows 10 playing a dx11 game, any news on that? ( i mean, besides the new api, like the 15% FPS difference between win 7 and 8 in BF4 for instance)

    Its nice to see support for older series like the 'Fermi' (Thermi anyone?). But how is that relevant for dx12 games only. These cards are already out of date, so i'm not expecting great performance in 'yet to be announced' AAA games.

    And, is there a difference between a GTX480 and a GTX970 in DX12 capabilities?
