GAMEFEST 08: New version adds compute shaders for GPGPU; completely compatible with DirectX 10 hardware

Microsoft has revealed the first details on the latest version of its DirectX SDK at the Gamefest event in Seattle.

Chief new features in version 11 are the new Compute Shader technology, which allows GPUs to be used for general purpose computing; support for tesselation, allowing models to be refined and smoother up-close; and multi-threaded resource handling to help games utilise multi-processor set-ups more effectively.

Rather than require new hardware as DirectX 10 did, DirectX 11 will be completely compatible with DirectX 10 and 10.1 cards - but will, like its predecessor, only support Windows Vista.

Source: http://www.developmag.com/news/30218/Micro...eils-DirectX-11

Not entirely clear if it means it'll be software compatible (I.e. if you install DX11, it wont break anything, but you wont get the features of it - like previous versions of DX), or if it's actually fully compatible with current DX10 hardware.

If it's the latter, I'll be a very happy bunny =D

erm, hasn't every previous iteration of DX been compatible with older hardware? the real question is, like previous iterations, will dx11 feature only be available to dx11 cards?

Read the bold part. They only upgraded features software wise, no new hardware revision is needed.

They probably mean it'll work with current hardware.

Tessellation and GPGPU (think of Stream for ATI and Cuda for Nvidia, among other tools) are already possible on current hardware, and the multi-threading is in software.

Edit: And of course it'll require Vista, did people think it wouldn't?

This looks more like DX11 working on DX10 cards to add new features like GPGPU processing, physics, tessellation etc and more optimisations - not a bad thing at all. Also It is said DX11 is much more developer friendly.

Sorry to be a spoil sport but is anyone else starting to think DX11 is just a rebranding of DX10 to try and make it successful?

No because it's not the same API otherwise it would not have had the new features and optimisations...

.. more bad news for nVidia then as the current cards are not DX10 compliant this could mean no compliance with DX11 either..

Who told you this? this is completely wrong.... and you didn't read either because the nv cards are DX10 but not DX10.1 and DX11 works on both DX10 and 10.1 cards.

Is it me or it look like they are working on this way just because Dx10 failed?

Nahhh,where did you get that idea,DX 11 is the result of the constant evolution Microsoft is giving to their products,the idea is to stay way ahead the competition.

DX10 failed because Vista "failed".

I would say neither is true.

What competition? OpenGL? I think most games use DirectX these days, haven't played a game in OpenGL mode for... at least 8 years or so

I would say neither is true.

Hardware features usually take a while to absorb by the development industry. The typical development cycle for a game is longer than the time between Vista's release and now, which means that DX10 would've been an afterthought for the developers as they wouldn't have had a finalised SDK to play with.

My DXDiag show DX10 . .

I hope mine does too, I mean it should. My laptop does not, but it has an old Radeon 9600 which only supported DX9 so I'm assuming that's why. But I haven't checked the dxdiag for my new desktop so it better show DX 10.1 there when I check.

You never played any Doom3 based games? (Prey, ET: Quake Wars, Quake 4)

Sure OpenGL isn't popular on Windows, but I'm sure you played a OpenGL game in that 8 year lol...

      While I agree with all that, it just proves there's an a** built for every seat.

      Lol are you mad because I'm not using AI? I'd rather pay people than lose a bunch of potential customers and get humilated because I used AI. A lot of people won't purchase a game if it used AI during development.
    • LibreWolf 152.0-1

      LibreWolf 152.0-1 by Razvan Serea LibreWolf is an independent “fork” of Firefox, with the primary goals of privacy security and user freedom. It is the community run successor to LibreFox. LibreWolf is designed to increase protection against tracking and fingerprinting techniques, while also including a few security improvements. This is achieved through our privacy and security oriented settings and patches. LibreWolf also aims to remove all the telemetry, data collection and annoyances, as well as disabling anti-freedom features like DRM. LibreWolf features: Latest Firefox — LibreWolf is compiled directly from the latest build of Firefox Stable. You will have the the latest features, and security updates. Independent Build — LibreWolf uses a build independent of Firefox and has its own settings, profile folder and installation path. As a result, it can be installed alongside Firefox or any other browser. No phoning home — Embedded server links and other calling home functions are removed. In other words, minimal background connections by default. User settings updates Extensions firewall: limit internet access for extensions. Multi-platform (Windows/Linux/Mac/and soon Android) Community-Driven Dark theme (classic and advanced) LibreWolf privacy features: Delete cookies and website data on close. Include only privacy respecting search engines like DuckDuckGo and Searx. Include uBlockOrigin with custom default filter lists, and Tracking Protection in strict mode, to block trackers and ads. Strip tracking elements from URLs, both natively and through uBO. Enable dFPI, also known as Total Cookie Protection. Enable RFP which is part of the Tor Uplift project. RFP is considered the best in class anti-fingerprinting solution, and its goal is to make users look the same and cover as many metrics as possible, in an effort to block fingerprinting techniques. Always display user language as en-US to websites, in order to protect the language used in the browser and in the OS. Disable WebGL, as it is a strong fingerprinting vector. Prevent access to the location services of the OS, and use Mozilla's location API instead of Google's API. Limit ICE candidates generation to a single interface when sharing video or audio during a videoconference. Force DNS and WebRTC inside the proxy, when one is being used. Trim cross-origin referrers, so that they don't include the full URI. Disable link prefetching and speculative connections. Disable disk cache and clear temporary files on close. Disable form autofill. Disable search and form history...and more. LibreWolf 152.0-1 changelog: Upstream release, see the Firefox 152.0 Release Notes Notable changes: The AppImages are now built on Codeberg along with the other releases We have decided to wait a bit longer to enable the settings redesign, due to use being aware of multiple upstream issues Download: LibreWolf 64-bit | Portable 64-bit | ~100.0 MB (Open Source) Download: ARM64 | Portable ARM64 Links: LibreWolf Home Page | Addons | Screenshot | Reddit Get alerted to all of our Software updates on Twitter at @NeowinSoftware

      hahahahah wow hahahah you sure got me there hahahahahah, you know that bad performance is always due to poor optimization by the developers, right???

      "I know for a fact I'll never own one of these." This is why choice is better than government regulation. Globaly Android has something like 72% of the smartphone market. Granted the vast majority of that is low end phones. Apple can and should charge whatever they want. The market will decide if it is too much.
