No redistributable runtime for now

Microsoft launched its much anticipated Windows 7 operating system last week to great fanfare. One of the features of Windows 7 is DirectX 11, which is a superset of DirectX 10.1 already used in Vista Service Pack 2.

Windows Vista introduced the Windows Display Driver Model (WDDM), which allowed new features such as virtualized video memory and scheduling of concurrent graphics contexts. Windows 7 also uses WDDM, albeit a newer version.

Microsoft had promised that Vista users wouldn't be left in the cold, and would be able to download and use DirectX 11. It included DirectX 11 in a beta version of its "Platform Update" available in September. The final version is now available via Windows Update.

The Platform Update is meant for computers running Windows Server 2008 SP2 and Vista SP2, and is composed of four parts: The Windows Graphics, Imaging, and XPS Library contains DirectX 11, DirectCompute for hardware accelerated parallel computing, and the XPS Library for document printing.

The Windows Automation API "enables accessibility tools and test automations to access the Windows user interface in a consistent way across operating system versions".

Windows Portable Devices Platform is a basis to standardize data transfers between applications and portable devices such as mobile phones, digital cameras, or media players.

The "Windows Ribbon and Animation Manager Library" enables the use of Microsoft's "Ribbon" to be used by other programs and provides a framework for managing the scheduling and execution of user interface element animations.

Unfortunately, Windows XP users will still have to stick to DirectX 9.0c, as the older OS does not support WDDM.

Microsoft usually makes a redistributable DirectX runtime available to developers and for download. It is meant for computers without an internet connection or for users who have multiple computers, and is often bundled with games. The current redistributable is from August, and there is no word on when an updated runtime will be available.

I'm confused...

So I have Vista on my work laptop... (which is actually a Sony "gaming" laptop, even has a Blueray burner)... what does having dx11 offer?

I could only assume you need a DX11 video card to use this...which probably excludes 99% of Vista users.

all the memories that movie brings back....good times back then ...

Back in the late 80's my friends and I quoted the crap out of that movie it was a mainstay of much joking around considering we all played guitar in one of our bud's garage all the time after school (oh we had someone on drums too but we weren't a real band) the movie just fit well into how we were and what we did back then.

for you on your laptop, nothing.

do use DX11 you will need to get the new ATI 5XXX series cards.

Support for Shaders 5.0 is only one of features of DX11.
DX11 introduces so called Compute Shader - set of API functions that can be used by GPGPU programs. Shaders 4.0, 4.1 and 5.0 are supported by Compute Shader. DX11 also has support for multi-threading. It can help programs that use DX11 in better utilization of multicore (and/or multiple) procesors if they are present in system.

You missed out Tessellation -

For the short term atleast, this will be the most impressive and most noticeable feature of DX11 games.

I've not missed Tessellation.
Tessellation is feature that requires DX11 hardware. I was talking about features that could be usable in conjunction with older hardware.

On Laptop, not much use. But if you have a desktop Vista installation and bought a new DX11 graphics card, but didnt want to upgrade to 7, then it helps

Well I won't be right away at least. I did pre-order $50 copy of home premium but it is currently lying unopened on my desk. I didn't have a machine with Vista installed until last June. And I have to say I haven't had a single issue with anything. I guess I missed all the issues. I wish it was launched in close to it's current state as it could have been favorably remembered OS.

It's not essential as you think, if your PC if fast enough for Vista, 7 doesn't offer much improvement.

I updated from Vista 64 to 7 64, and got a few bluescreens now. I should have waited for more mature drivers.

If they can't legally get a free 7 upgrade, and would prefer not to run a pirated copy of 7, then it makes sense to stay with Vista if it does everything you want it to do satisfactorily.

I'm still on XP because it does everything I want it to do perfectly fine, though I do have a 64-bit Vista Ultimate partition I use occasionally (mainly for running 3DMark Vantage)...

Nothing, yet.

For me, it's easy. I won't upgrade untill i install a game that requires me to upgrade to DX11.

Pretty pointless if the software doesn't make use of it yet.

I hope everyone will realize that DX11 is really a subset of DX10.1. The majority of the features of DX11 is compatible with DX10.1 hardware (Radeon HD 4800 series since nvidia decided it wasn't important enough). Some of the bigger features of DX11 do require new hardware though such as hardware tessellation and the compute shader (the compute shader "will" work on DX10.1 hardware though, but will have better performance on DX11 hardware obviously).

Um, no. DirectX 11 is a superset of DirectX 10.1. DirectX 10.1 is a subset of DirectX 11. This is talking about the features of the two.

The hardware that can run DirectX 11 is a subset of the hardware that can fun DirectX 10.1. So, you're right, there will be no incompatibilities with running DirectX 11 on hardware only capable of DirectX 10.1 (or just about any older version of DirectX for that matter).

Superset, subset, either way, DX11 is an extension to DX10.1 lol. Just got the 2 words mixed up.

I don't follow, all that DX11 being a superset of DX10.1 means is that it will retain all the DX10.1 API's. That being said, DX10.1 cards will not be able to do anything beyond that, they are not 'compatible' with new features found in DX11. Its just a smart way to do things, instead of starting from scratch giving devs little incentive to program for hardware that nobody can use (ie. the move from DX9 to 10). This is where the compatibility comes in, developers can make DX11 games that people with DX10 cards can play, it will still look like DX10, but at least the compatibility is there giving devs that extra incentive.

Umm...if there's no such thing as a Blu-ray burner, how do they create movie discs? Unless you're stupid enough to think the discs are created with the movie on it.

Blu-ray burners can be bought, they're just expensive.

actually, they are. when a movie disk, or a game DVD is to be manufatured in mass, a master is made and is used to then "stamp" out copies. it is a physical stamping/making process, not a burning a disk process like you would do at home.

You might want to read more.....

Of course blu-ray burners exist...where have you been? Under a rock for the last year at least....
