Directx 12 to not support Windows 7.

The difference is the meaning of the words. You and amd fans use it to mean that win 7 will be unsupported by ms. Which in turn means win 7 users need mantle to keep up with dx12 and win10 users. All to paint a picture that in the pc world only amd has the end user at heart

No, they will just be pushed to buy windows 8.

Win 8.1 with Classic Shell is fantastic, and I was a die-hard Win 7 fan!!! Not seen the Start Screen or any Metro apps yet too thank God (2 month install) ;) :D

Tried Win 8 last year not to bad uninstalled it and waited for it mature.

So today l installed 8.1 what a good improvement its on to stay.

Quick and easy to install, super smooth, vibrant colours, easy to use.:)
 
Shock as 5 year old OS doesn't get latest stuff, I mean it's not like they made it easy for people to upgrade by offering W8 dirt cheap at launch or anything... :P

If there are 50million windows 7 and 8 users who can all use Mantle, and only 5 million Windows 8(if it's on that) and Win 10 users who can use DX12, which version would get priority? As and when Mantle will also be available on multiple platforms that DX isn't and won't be available on. It's like they are going out of their way to give game devs a reason to favour Mantle.

At some point Mantle will likely work with at the very least AMD gpu's, but free for Intel and Nvidia to make drivers for, on Windows, Android and Linux/SteamOS. Having DX12 available asap across Windows versions would give dev's less reason to think .... well, Mantle will actually be available to more people than DX12... which will we now put the most effort into. Potentially work on Mantle, tell nvidia they will have to support it or wait for DX12 support, do one set of work and have it work on Steam OS with little to no extra effort.

MS should be making it as seamless and easy as possible to get to DX12 for everyone right now, anything else is borderline retarded.

50 million Mantle users? Nope. Valve announced back in September 2014 that Steam broke milestone of 100 million users registered to play games and EA Origin userbase surpassed 50 million users as of July 2013, probably still over 50 million users now.

Accorded to Steam hardware survey here are 17.36% or 17.36 million AMD GCN GPUs capable to run Mantle API, 62.38% of it or about 10.82 million are Windows 7 users, 30.82% of it or about 5.35 million are Windows 8 users. 81.72% or 81.72 million Nvidia GPUs based on Fermi, Kepler and Maxwell are capable to run DirectX 12 which is the largest userbase easy outnumbered AMD GCN userbase capable to run Mantle. Also there are 5.24% or 5.24 million Intel CPUs with Haswell HD Graphics 4200, 4400, 4600, 5000, Iris 5100, Iris Pro 5200, Bay Trail HD Graphics, Broadwell HD Graphics 5300, 5500, 5600, 6000 and Cherryview CPUs will supported DirectX 12. Combined all Nvida, AMD and Intel together will see 104.32% or 104.32 million gamers have GPUs that will be ready to run DirectX 12 games which is incredible massive. Mantle have very long way to go to catch up but I think AMD will abandon Mantle in few years like 3dfx did with Glide.

Here was 2,538,354 PC players total played Battlefield 4 since 1 May 2014, 17.36% took from Steam hardware survey calculated about 440,658 probably run on Mantle API. Peak 40,637 played online over last 24 hours on 1 May 2014 accorded to BF4Central.com.

Also here is DirectX 11.3 Microsoft revealed it at Nvidia Maxwell launch, it will release after Windows 10 launch, DirectX 11.3 is high level API supported all Mantle and DirectX 12 features which will be very easy to write code at high level vs DirectX 12 low level which will be very hard to write code. DirectX 11.3 is aimed at developers and programmers who had lots of experiences on high level API and DirectX 12 is not suitable to them because of very little or no experiences. Code at low level API is aimed at advanced people who had lots of experiences on consoles and Mantle. Here are no details which GPUs and whether Windows 7 and 8 will supported DirectX 11.3 yet.

I wish I had some of what you are on sometimes. Some crazy numbers there.

Rough estimates put the Windows 8 userbase currently at about 150 million installs. Far more than the entire desktop *nix and OSX user bases combined. Added to the continuing rumours that Win 10 will be either free, or at the very least a very cheap upgrade for existing 7/8 users. I don't think there will be many worries about the available install base of DX12 not being the primary focus for developers (I'd imagine Microsoft are already building Xbone development kits around this new version of DX). I'll wager that within 3 months of DX12 being made available to end users, the number of PC's that support it will exceed the number of machines with Mantle support (remember DX12 will be supported on all NV hardware going back to Fermi, and all DX11 capable Intel IGP's).

Windows 8.1 is still stated to get feature updates for many years to come (unlike 7) so I don't think there will be many worries about DX12 not being made available for that platform. In addition to the fact Nvidia wont touch Mantle with a barge pole, Intel being rubuffed and going away to make DX12 demos instead, absolutely no software vendor is going to ignore an install base of that size to prioritise Mantle. So things will continue to prioritise DX as they can hit all hardware with a single code base. Any thing in addition to that, is just that.

I do find it strange that people think Microsoft should support and develop new features for older operating systems in perpetuity. Try running new Mac software from Apple on a version of OS X that's only a few years old. Windows 7 will be at least 6 years old when 10 hits. I don't want software that old holding back the latest OS. Heck, even 8.1 is a much better OS for gamers than 7, just spend a few quid on Start8 and you have a superb OS that beats 7 in every aspect.

Your estimates on Windows 8 userbase size is incorrect. Microsoft at Goldman Sachs Technology & Internet Conference on 13 February 2014 confirmed Windows 8 licenses surpassed 200 million milestone in 15 months after launched in 2012, estimated Microsoft sold around 13 million Windows 8 licenses each month. Probably over 300 million Windows 8 licenses sold by now but that not all! Heard of Windows 8.1 for OEMs called Windows 8.1 with Bing? :) Intel is shipping 40 million $99 tablets by end of 2014 included Windows 8.1 with Bing which is free to OEMs for tablets cost $99 and less or less than 10 inch screen, Mini PCs and NUCs. By end 2014 combined with 40 million Windows 8.1 with Bing would see Microsoft achieved nearly 400 million Windows 8 licenses. I found Zotac sell Mini PC models ZBOX ID18, ZBOX CI320 nano, ZBOX CA320 nano and ZBOX BI320 all bundled copy of Windows 8.1 with Bing.

Microsoft stopped mentioned about how many Windows 7 licenses sold now, Steven Sinofsky was mentioned 670 million windows 7 licenses sold at New York City's Windows 8 launch event in October 2012. They stopped selling Windows 7 retail versions on 31 October 2014, OEM and retail versions mainstream support will end on 13 January 2015. Hard to say how many licenses will be sold by end of Windows 7 life in 2 months so I could guessed 1 billion Windows 7 licenses. In fact 1.5 billion people use Windows everyday, that 1.5 billion Windows licenses total accorded to Microsoft by the Numbers website.

Not surprised, I don't believed everything Richard Huddy said, he misspoke or talked nonsenses too many times with tessellations, CUDA, PhysX, Microsoft abandoned DirectX, Mantle, Nvidia Gameworks and now this DirectX 12.

Nvidia Gameworks now officially supported on PS4 and Xbox One to make easier for developers to add effects quickly to cut development times or shortcut after coded effects themselves turned out not worked or not met artist visions, developers admitted coded physics are bloody too difficult and needed lots of experiences so added Nvidia Gameworks made life a lot easier for developers.

It made me wonder why AMD hired Richard Huddy and why didn't AMD fired him.
 
I dont hate win 8 as much as i thought i would when i first got a laptop with it. It took a while to get used to but overall its not that bad, and has some useful features. I still use win 7 on my gaming pc though.

Im not that suprised that they will only put dx12 on win 10, its only logical. and after any teathing problems it will turn out to be a good OS
 
by the time Win10 comes out, it will probably be the next good OS and most people will gravitate towards it. Bout time been using 7 for long enough and dislike 8 but some extra free performance gains would be lovely
 
To be expected but the upgrade itch got to me already. Using the Windows 10 technical build so far and I expect come commercial release this OS will go from strength to strength.
