Microsoft to Talk DirectX 12 at GDC

Microsoft will present its first paper on DirectX 12, its next-generation multimedia API, at the Game Developers Conference (GDC), on the 20th of March, 2013. The event could include presentations by NVIDIA, AMD, Intel, and Qualcomm. It's not clear at this point if Microsoft will release developer tools and resources on that day, or simply outline the API to spur interest. If anything, it should gently nudge today's GPU manufacturers to make their future GPU designs ready for the API. There are currently no GPU families that we know of, which support DirectX 12. AMD's current Graphics CoreNext 2.0 GPUs, such as the Radeon R9 290X, support DirectX 11.2, while NVIDIA's "Maxwell" GPUs, such as the GeForce GTX 750 Ti, feature an identical API feature-level support to their "Kepler" predecessors.

If this twitter feed is any indication, then DX12 might be a software update of the present D3D code - specifically Xbone's current DX11.x iteration, in which case, present hardware should also be DX12 capable. If it isn't hardware dependant that would also indicate a fairly quick introduction.
If this the case, I wonder if DX12 makes it to primetime before Mantle gets out of beta.

If it works on X-Box One and current DX 11.2 AMD GCN 1.0+ hardware its most likely a Superset. AMD hardware will be compliant and Nvidia will be left with DX 11.0 & feature support ?

Unless developers see big incentives to go back and optimize for DX 12. We'll see the same thing as always DX 9/DX 10 game engines with MAYBE updated DX 12 features. Much like we see today with old DX 9 game engines incorporating DX 10/DX11 features.

So for the PC i'm building, I'm going all outta my way to get windows 8.1 for DX 11.2 when its not even being used? I might as well use 7 if that's the case.

GTX Titan Black supports the D3D11.2 API. Probably for the soul purpose of selling a cheaper Graphic Accelerator/Gaming Cards that didn't need the full 12 GB frame-buffer like the K40 Tesla. Anything before that doesn't support it. If you ask me, NVidia was hesitant to pay royalties for it in the GTX 780 Ti and it's predecessors. AMD's 7000 Series has had support on a hardware level for both D3D11.1 and 11.2. It eventually had full support from the software side through a driver update with the Win8 OS. NVidia mainly had support on a software level, but not the hardware level. Sadly, this is what you pay for your "premium price" in the past year with NVidia.


.
Both GTX 750 Ti "Maxwell" and Titan Black supports DirectX 11.2 feature level 11_0 i.e. no support for 64 slot UVA for all shader types.

http://www.msi.com/news/1665.html DirectX 11.2 (Feature Level 11_0) for Titan Black.

http://www.asus.com/in/News/4jZ47ImpuAL4DdMR "DirectX® 11.2 standard (up to API feature level 11_0)" for GTX 750 Ti.

AMD GCN, Intel Haswell and Qualcomm Adreno 420 supports Feature Level 11_1.

Looks like amd is going to be the clear winner lol and 2-3 posts above, keep posting your pix it just makes me lol
Good night all

Till tomorrow :rockout:


They have their work cut out for them.

X1's GPU hardware is in the low end side LOL.

Also read http://www.slideshare.net/zlatan4177/gpgpu-algorithms-in-games

Your benchmark doesn't cover real time GpGPU results return to the CPU latency and API improvements doesn't automatically solve GPU bound issues.

"For this first graph we are looking at Siege of Shanghai 64 player session. We are comparing at a common 1080p resolution, and without AA, but maximum in-game settings."

Keep posting how Mantle is good for 1080p and below resolution. : D

That's the only difference you see?

Now I know why you use that avatar.

That's the face one makes when they try to make sense out of your post. "WTF, Did he mean to say cause I sure as hell have no clue"

Interesting how you think if Xbox One supports DX 11.2 desktop GCN 1.0 supports it too. And totally ignoring fact that Microsoft demonstrated DX 11.2 tiled resources with GTX 770.

I would suggest he is likely correct in stating amd will be first out the gate with dx12 as the uarch Is the same as xbone simple as really.
And team green will likely be behind the blue (intel) team when it comes to full feature (or partial) support for dx12 ,,, why, because nvidia will likely want to sell the world a brand new gpu for that option as they always have.

Probably, but it's all PR bullet points for the most part. AMD were first out of the gate with DX 10.1, 11, 11.1, and 11.2, but it amounted to close to nothing in actual practical terms, and statistically, AMD have fallen further behind Intel (overall GPU market share) and Nvidia (overall discrete market share) during those four D3D iterations.

Wow you said something neg at me, that was imho, completely spot on.
I'd normally bicker with you but your right :)

Being compliant and supporting a subset feature are two different things.

Try reading sometime time rather then just spouting ignorance. It will definitely make you seam less of a jerk.

The underlining is if that trend continues adaptation for DX12 hardware is at minimal years away and game engines developed with or revamped to DX12 are years away as well.

The market has to be flooded with DX12 compliant hardware for the companies to take a interest in developing for it. Consoles don't have that issue.

All depends on what DX12 is capable of.

So please enlightening us where did you read that Xbox One and GCN 1.0 will support DX 12 and Nvidia will fall behind. From fake AMD slides?

Since you cant even match up who said what. Can you even read and understand anything to begin with?
Not only that your basing what ever delusional argument you have in your head on a slide from Dec 2012 and the Watch Dog game which hasn't even been release yet?

Your a fine example of a "Stay in school kids" PSA.

What difference does it make if its compliant if all the necessary features for 3d gaming are there?
