Microsoft Corp. said that it would not port DirectX 11.1 application programming interface (API) from its latest Windows 8 operating system to older OS platforms like Windows 7 and Vista. The move will help the software giant to encourage transition of performance and games enthusiasts to the new Windows 8.

“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. DirectX 11 was made available for Vista (bing it), but at this point there is no plan for DirectX 11.1 to be made available on Windows 7,” said Daniel Moth, a Microsoft employee, in a post in a Microsoft forum for programmers.

According to Neowin web-site, among other things DirectX 11.1 adds native stereoscopic 3D support, which means any video games or applications written with DirectX 11.1 will have support for viewing the content via stereoscopic 3D glasses out of the box. By contrast, currently game developers have to work with graphics card hardware designers and tailor their code for particular implementation of stereo-3D. Therefore, those, who want to play the forthcoming PC games with native S3D will have to upgrade to Windows 8 first. This means that the latest operating system will be a must for hardcore gamers in about a year time, if not earlier.

From time to time Microsoft limits compatibility of new APIs with older operating system platforms for technical of marketing reasons. For example, Microsoft did not port DirectX 10 API to Windows XP operating system back in 2007, which forced many PC enthusiasts and gamers to upgrade to Windows Vista to enjoy the latest games which utilized DX10 API. On the other hand, Microsoft did port DirectX 11 to Windows Vista once the former became available.

The reason Microsoft ported DX 11 to Vista was because everyone had plenty of reasons to get off that OS, and hated Microsoft for making it. With XP and Windows 7, people are generally not unhappy with it, so little stuff like this is Microsoft's way of trying to push people to use something they otherwise wouldn't be interested in.

That makes no since at all. If they wanted people to get off Windows Vista, then they wouldn't have given it the update.

What is wrong with you?

Think before you post, if you can.

They would always prefer to move people to the next OS, it makes them money. With me so far?

Windows XP was an OS they liked. They had to stop upgrading it, so more people would go with Vista. Got it?

Vista, like you, wasn't very well liked. People moved off it anyway, and Microsoft looked like a good guy moving other technologies to it. Also, they were more interested in getting people off XP, which was still the dominant OS. Getting people off Vista was easy, it sucked.

Windows 7 is well liked, so Microsoft better stop upgrading it, so people will get Windows 8.

Got it? If the OS sucks, people leave it behind anyway, if it's good, they don't offer upgrades to create reasons to move off of it.

You really can't understand that?

whats wrong with him ? apparently nothing.

its your comprehension of what he typed thats apparently lacking Maza,but no matter, he said MS ported DX 11 to Vista TO try and make xp user's move to Vista/or STOP USERS dumping that Vista version of their OS and returning to XP depending on how you read it OC.

it didn't work OC as Vista was and is crap, but it does have DX 11, unlike XP that could also use DX11 if they actually back ported it there too, but they wont.

not that any of this "Native_Stereo_3D_Output_Is_Exclusive_for_Windows_8." really matters anyway as the OSS Encode/Decode apps devs x264/ffmpeg/avconv already wrote and so all their 3rd party downstream apps can also use the best visual quality generic Stereo 3D (8bit/9bit/10bit) encode/decode patches from the official specs long before MS even sold windows 8, and its cross platform too.

emphasis mine.

I wonder if Windows 8 will get the same treatment from Microsoft when it fails?

probably ,but then Direct Compute and OPENCL on x86 is a real mess non of them cut it for real HQ video encode for instance in their present forms as the right integer SIMD,SAD microcode etc is not in the gfx cores today to run the best algorithm's and the slow PCi-E bus just slows everything down to much passing the decoded data back to the CPU side for processing too.

so its probably up to the masses of ARM commercial vendors to now make it usable for something Compute generic on their mali T6xx kit etc so DirectX 11.1 is pointless on x86 Linux and probably ARM linux too right now unless its good for fractal based algorithmic super HD video frame de-noising etc perhaps.

Micro-suck for zombies, the masses are fleece sheeple dumb-down idiots.
