DirectX 12

So as expected Nvidia were not sat around, and mantle was not the second coming that pushed Nvidia and Microsoft to act. I am sure I said something like this the other day ;)

You really think without Mantles launch we'd be expecting DX12 in 12-24 months? I'm not so sure. It may have come eventually, but clearly their hand was forced. Even the article in the OP admits as much.

I want to know what they were doing for 4 years. Sitting around having a few cups of tea by the looks of it. By the time dx12 is released it will be close on 6 years. Anyhow it's been said by Microsoft that they were also working on it with AMD. Amd then released Mantle so AMD must not think all that much of dx12 or they have other plans for it.

How long has mantle been worked on LT btw?

Mantle took two years to create as far as i know. That four years sounds a bit like PR to me. If DX12 was in the pipeline im sure MS would have had it ready to launch with the Xbox One. They may have had something planned and may have already started work on it. Truth is we'll never know the proper truth i doubt, shrouded by PR. But four years? I doubt it. That would mean 6 years to create dx12.

Obviously Nvidia / Microsoft weren't just sitting around, but if you think Mantle and the developers embrace for the low overhead API didn't directly influence MS and Nvidia to get a move on then you are a turnip :p

Mantle lit a fire under them, it's win win for gamers in both camps..
 
Thanks i couldn't remember how long AMD spent :)
Not sure on how long it would take to write, i'd imagine DX is a bit more involved than mantle especially if its truely cross platform and i doubt they will release it in Alpha but MS can also put more resources onto it than AMD so i'm not sure.
Xbone would have had to been delayed for it and they wanted a release at a similar time as PS4

That's the point though as you would think Microsoft along with help from Nvidia and AMD could have got something out inside 4 years. If they were going full steam ahead on dx12 it probably would have been released in time for the Xboxone.
 
So in the last few pages this DX12 thread has gone through a 'discussion' on which graphics card vendor sells the most GPUs and now we worried about if AMD get to take any credit for DX12 (which I think some predict is pure evil in software form)?
This is what happens when we get drip fed info and then products aren't released immediately!

Speculation is pointless, in the end as it won't change the outcome and we don't know what to believe. We just end up with arguments about is Mantle = DirectX 12?
At one point we thought it might be and it was praised. Now we not sure sure and all of a sudden AMD have gone from giving MS Mantle to having made Mantle because DX12 doesn't seem like it will be any good.

Do we actually know anything more that is close to being factual rather than speculation about this yet?

What we infact know for certain= MS has announced in the future there will be a version of DX12.
Other than that we are guessing/hoping speaking words of wisdom from a friend of a friend that knows a guy that talked to a dev that said this might be the case :p
 
DirectX 12 Requires New Graphics Cards to Utilize All Features

Last week both AMD and NVIDIA were making the media rounds with the welcome news that Microsoft’s latest DirectX would be supported by current generation graphics cards. AMD has stated anything with their GCN architecture has native support for DX12 and any series released after NVIDIA’s Fermi architecture will have support the API as well. Today though we learned these graphics cards will have only limited support for the API, with key elements missing.

AMD talks DirectX 12

DirectX 12 will do in 18 months what Mantle does now

Our industry insiders keep telling us that ever since Mantle got introduced AMD got itself in quite an awkward situation with Microsoft's DirectX team. Mantle obviously performs better than the industry standard DirectX 11 and the introduction of DirectX 12 that as well as Nvidia's angle on DirectX 12 are shedding some light on what is to come with DirectX 12.



AMD obviously voiced its support for DirectX and was happy to say that all Radeon GPUs powered by its latest Graphics Core Next (GCN) architecture will support DirectX 12. This includes Radeon HD 7000 Southern Islands 2012 GPU generation as well as 2013 / 2014 Volcanic Islands R200 series.

AMD uses the words "full compatibility," so there won't be any mistakes there, but the official support will be announced at a later date. We are talking about DirectX 12 drivers, but since we don’t expect games before the 2015 holiday season, AMD has a lot of time on its hands. Nvidia did announced that it has some drivers and DirectX 12 developer's kits that were sent to its top developers, but AMD chose to remain silent on such a move.

"AMD strongly believes in the benefits gamers and game developers can realize from lower-overhead API development," said Matt Skinner, corporate vice president and general manager of Graphics Business Unit at AMD. "With the Mantle API, AMD has shown the world our commitment to incredible performance, and we look forward to enabling the same performance gains by supporting the industry-standard DirectX 12."

This is Skinner's way to say that he is glad that Microsoft is doing what AMD started, as lower overhead is the essence of both AMD Mantle and future DirectX 12. We are glad that DirectX 12 is a real thing and that it is finally coming. It will make good use of 20nm GPUs that are significantly faster than the ones we have today, but Mantle will speed them up even before we see DirectX 12 games on shelves.

Well this sucks. (although by the time DX12 reaches us, i expect most of us will have upgraded)

Last week both AMD and NVIDIA were making the media rounds with the welcome news that Microsoft’s latest DirectX would be supported by current generation graphics cards. AMD has stated anything with their GCN architecture has native support for DX12 and any series released after NVIDIA’s Fermi architecture will have support the API as well. Today though we learned these graphics cards will have only limited support for the API, with key elements missing.

According to TweakTown current generation graphics cards will not be able to use the new blend modes and conservative rasterization features. In order to use these features you will have to upgrade to AMD’s Radeon Rx 300 series, or NVIDIA’s second generation Maxwell architecture.

Speaking in an interview with amd, amd gave microsoft and other partners the full specifications for mantle early on in its development cycle, and dx12 was influenced by Mantle (aka push to reduce api overhead was a result of competition from Mantle).

AMD Respond

There has been a lot of rumors and speculations flying about the internet regarding the origin of DX12. Many have cited that Microsoft effectively ripped off Mantle, while others (particularly MS) are keen to point out they’ve had DX12 in development for around four years now. I spoke with some sources at AMD to get a little information regarding this.

RGT: Can you provide some insight into the DX12 vs Mantle debate? Clearly Mantle has some major advantages regarding lead time and the ability to work on a variety of different platforms, instead of being pushed onto only Windows. Do you believe that Mantle’s support from developers will be helped largely due to its ability to run on Linux in the future?
Robert Hallock: I believe that Mantle’s current principal advantage is in its very nature: a low-overhead API. It’s the only low-overhead API available on the market today, and it’s a proven technology supported by four game engines and a number of games. If you’re a game development studio that wants to become familiar with low-overhead API development, Mantle is the only game in town and we’d love to hear from you!
RGT: There are many who’re claiming and reporting rumors that MS ‘copied’ parts of Mantle’s design and effectively re-branded it. Can you comment on this or perhaps provide a little insight?
Robert Hallock: DirectX 12 is Microsoft’s own creation, though they have welcomed input on its development from many different technology partners including AMD. We have welcomed the same input on Mantle by sharing the full specification with Microsoft since the early days of our API. As the industry moves to embrace the principles of ‘closer to the metal’ API design, it is evident that our pioneering work with this concept has been highly influential.
