For Now, DirectX 11.1 Will Only Be for Windows 8

By - Source: Eurogamer | B 79 comments

For now, DirectX 11.1 will be a Windows 8 exclusive.

Microsoft's Daniel Moth revealed a few months back that DirectX 11.1 will be a Windows 8 exclusive – at least initially. The revelation arrived by way of the Microsoft Answers forum in response to questions about using the WARP accelerator and understanding the software stack C++ AMP is built upon.

"With DirectX 11.1, WARP was enhanced with (among other things) support for DirectCompute and hence it is one of the accelerators for C++ AMP. DirectX 11.1 is part of Windows 8, just like DirectX 11 was part of Windows 7," Moth answered.

Originally DirectX 11 was eventually made available on Windows Vista too, but for now Microsoft has no plans of doing the same and bringing DirectX 11.1 to Windows 7. "Should the plan change and either DirectX 11.1 as a whole, or WARP on its own, was made available on Windows 7, then you would have this available to target from C++ AMP," he added.

According to the post, WARP is a high speed, fully conformant software rasterizer. It's a component of the DirectX graphics technology that was introduced by the Direct3D 11 runtime. Moth describes it as a component of Windows 8 that can be shipped on other platforms, but currently there are no plans to do so.

One of Microsoft's big push with Windows 8 is in the platform's gaming capabilities. The Games app brings to the user front and center seemingly everything Xbox Live gamers have enjoyed for years. Games can be purchased for either platform, and achievements can be shared with friends and family spanning simple games like Solitaire to Call of Duty: Black Ops 2.

Making DirectX 11.1 exclusive to Windows 8 seemingly pushes PC game developers into embracing the updated platform if they want to utilize those features. Various developers have expressed their distaste for the built-in storefront, but now that we're weeks into the platform's release, there really doesn't appear to be anything to stress over. Gamers can still purchase their games from Steam, GameFly, GameStop and more as if they've never left the Windows 7 desktop.

To show what Windows 8 can do, we can only dream that Microsoft would green light a version of Halo 4 that takes advantage of DirectX 11.1 and the new Metro UI design.

    So what will DX11.1 offer than DX11 doesn't?

    WoW bryon could you be any more of a fanboy.

    Give me a break win 7 is far from obsolete this is simply MS trying to shove people into updating to windows 8. Which won't work anyways, and they'll soon get enough backlash to make work for windows 7 also.

    And if they're gonna be like this I have no problems getting a windows 8 for free. Of course I don't see dx 11.1 becoming mainstream for awhile anyways, so Ill stick with a perfectly good windows and laugh at all the idiots like yourself.

    I have a feeling that DirectX 11.1 might be as useless an upgrade as Windows 8 is.

    If M$ thinks that makes me upgrade some 50 business PCs to windows 8... well, guess again :-)
    If anything, it will have the opposite effect.

    A few blades of grass for Winsheep to graze on. That and further attempts to keep developers from contemplating the use of OpenGL.

    This does not seem like a good idea to force people to upgrade to windows 8 just because people are going crazy to upgrade.

    Considering that most games still use the anitquated DX9 (thanks a lot consoles lol) this is a non issue. Besides if M$ was truely interested in the PC gaming scene they would have released the rest of the Halo series a long time ago for the PC. With everything lately they really don't give a rats a$$ about PC gamers other than wanting us to upgrade to Windows 8, and that's really not going to happen in any significant numbers.

    I see 11.1 being as relevant as 10.1 was. If it takes that much money for an OS upgrade for that minute feature set, then Microsoft's business model from Vista and up is unnecessary. Microsoft is just trying to find the right carrot to entice resisting users to buy their upgrade, we all know that 7 and even Vista is not incapable of running 11.1 as they all run on the same underlying architecture.

    @Bryon, Windows 7 is far from irrelevant. Windows 8 is widely viewed as a sidestep and not an upgrade in any way except for their tablets and phone (what Windows 8 is obviously designed for anyway). Not to mention, most businesses will continue to run Windows 7, Vista, and even XP for several years to come as most will not touch an OS until at least SP1 comes out . When an OS does what it is designed to do and works well for the user's need (something MS lost an understanding in), then they are not apt to upgrade nor should they feel they have to for that reason alone.

    In other words, any Windows game developer not writing Metro apps will stick to targeting DirectX 9.0 and/or 11(.0), and ignore 11.1. Seems pretty straightforward to me.

    Remember that backporting DX 11.1 takes resources and MS themselves may not believe there's enough changes in DX 11.1 to warrant that effort.

    DX9.0? Why not DX9.0C which is better and still fully supported even by XP?

    i have an Intel i5 2500k oced to 4ghz, ati 5870 oc, 8gb ram ddr3 1866mhz, samsung 830 128gb..
    and i was really happy with my windows 7..

    then i installed windows 8 and i have to admit, apart from metro likeness or not, that they are way faster. What do i mean? i didn't expect to see a difference in performance on the OS by jumping to windows 8 and when i prepared everything i must say! you can see a huge difference in speed, on loading programs games and switching to desktop/metro etc.

    At least the memory management is way way better, couldn't believe it was possible for example,
    when you right click "my computer" and select "manage" ..how long does it take to load the management console?
    At windows 7 it takes some noticeable time (compared to other tasks) however at windows 8 its almost instant!

    I had some strange freezes on various games (more like lagspike feels ) and i knew it was from overclocking (some games don't like OC ). At windows 8 it is almost unnoticeable.

    Now DX11.1 , is most welcome, not because it will make people upgrade blablabla but because of the
    "With DirectX 11.1, WARP was enhanced with (among other things) support for DirectCompute and hence it is one of the accelerators for C++ AMP"

    Meaning , smaller PCs with just onboard intel or amd apu will perform way way better than on windows 7! for example netbooks and now that i think about it, it's time to test win8 on our netbook ^^

    As much as I like Windows 8, your experience seems more founded in that your Windows 8 installation is a fresh installation and your Windows 7 installation is not. Well ,that's what it seems like to me based on the difference on performance supposedly being huge. They should be very close.

    When games start heading to Linux via Valve/Steams lead, this will be considered another nail in MS's home computing coffin.

    I was on a fresh Win 7 and now I am on a fresh Win 8. I can mirror his statements. While raw FPS didn't change much other things such as the general responsiveness of Windows and the speed at which things launch is far better it also stays more solid and fluid with a lot of crap opened. Sure I had to push it to the extreme in Win 7 to get it to bog down a bit but I run a setup with 4 monitors and do a lot of work and crap from my PC. Having a shit ton of programs and games open at any given time is the norm for me. As for the stability I personally no longer overclock so I cannot comment.
