Windows 10 update enabled DirectX 12
Interesting, if you have been playing around with the preview build of Windows 10, then you will have noticed that after you updated it to the latest build it now has DirectX 12 support. If you look at the screenshot below, you can see that it is enabled in the OS itself.
Now unfortunately there are no further drivers let alone software to test DX12. You will need a DX12 GPU (for all DX12 features), a DX12 Driver and then a game or benchmark that has DX12 support.
DX12 will add a lot of new features, but the most important one is significantly reducing overhead, much like Mantle making it dar more CPU friendly. BTW to make it clear, the biggest imporvement is reducing CPU overhead, you will need DX12 for that, but a DX12 GPU for that is not needed. The codebase simply is different and you will reap the benefits here even with a DX11 GPU.
If you like to give the Windows 10 preview build a try:
Microsoft has released another Windows 10 build for the Windows Insider program and this release brings with it a plethora of new features including Cortana, Continuum and a bunch more. To upgrade to the new build, follow the steps with your install of Windows 10 9879 or you can download the ISOs using the links at the bottom of this post.
- Click on the start menu and in the search box type 'Windows Update'
- Chose 'Windows Update Settings'
- In the left panel click 'Preview Builds'
- Click on the 'Check' now.
- Download the new build
After you do this, if there are bits to download for your machine, the process will start and then the waiting game begins.

That being said - how many DX12 hardware features do you think would work on the R5/R7/R9 2XX series? I still can't seem to get a complete answer on that.
Considering modern consoles are based on the RX 2XX series, I'm not TOO concerned about games that use DX12 hardware features incompatible with my GPU.
Yeah I kinda wish Hilbert or someone would do a write up on what is supporting what. Basically as it stands now there are "5" new major features coming with DX12:
Rasterizer Ordered Views
Typed UAV Load
Volume Tiled Resources
Conservative Rasterization
And the "5th" being low level access. (I'm calling that a feature).
Now it's also stated by Anandtech that "It should be noted at this point in time this is not an exhaustive list of all of the new features that we will see, and Microsoft is still working to define a new feature level to go with them"
So there could possibly be more.
For Nvidia, AFAIK, all cards Fermi and up will support the low level access feature. Maxwell supports all 5 features. As for newer features that Microsoft has yet to talk about, I have no idea if Maxwell supports those or not.
For AMD, AFAIK, all cards R7+ will support low level access. As far as the others, I don't think they've specifically stated that R9 can support those features but Mantle does implement some of them. For example "Volume Tiled Resources" is essentially the same thing as "Partially Resident Textures". The other features are also partially/fully integrated via other methods with GCN/Mantle. I'm pretty sure they can extend those features to support DX12 -- which if that's the case any card that has Mantle support should technically have full DX12 support. (Again, this is just my theory).
But yeah -- Hilbert if you could get in contact with AMD/Nvidia and get a definitive answer on what is supporting what I think that would be interesting to see.
Edit: And then another question I guess I'd have is -- what incentive do developers have to implement these features via software on older generation cards?
I mean let's say UE4 supports DX12 and Epic decided to do some low level optimizations Maxwell, maybe some of those will be compatible with Kepler because the architectures are similar -- but Fermi? I mean DX12 is a huge burden to the software developer, which is why only big engines will support it, but are they really going to do heavy optimizations for architectures that are years old? I doubt it.

hmmm...thought this was already the consumer preview, MS just continues calling it the tech preview.
But you are right, absolutely no need to show off DX12 when there is not even a tech demo using it available.
Besides, the 8.1 drivers are working flawless.
Neither NVidia nor AMD are going to waste resources on Windows10/DirectX 12 drivers for public use before Windows10 reaches consumer preview.

You're only getting some features of DX12. There's some features that require new hardware like the 9 series from nivdia.
Its funny how simple software update can bring DX12 to last generation GPU's.
