Thumbs up Now were talking! Direct X 11 To Use GPU For Parallel Processing

http://gizmodo.com/5028013/microsof...llel-processing

Direct X 11 To Use GPU For Parallel Processing


Quote:
Direct X 11 is coming, and it looks pretty awesome. Sure, you get advancements in shading and better support for multi-core machines, but what's really got our heads turning is the concept of letting programmers use the GPU in your video card to do some of the heavy lifting, meaning your graphics chip becomes a second, parallel processor. While the idea itself isn't new this is the first we've heard of Direct X using such technology and we're sure it'll have PC gaming fanboys drooling when it rolls out, whenever that happens to be.


Using the GPU for processing data is not exactly new, but having the weight of MS behind one standard way of accessing that power is what will FINALLY push this technology from a niche into the mainstream. Right now there is way too much BS concerning what brand of videocard you have (i.e. stuff like Gelato obviously wouldn't work with ATi cards) and then what model card you are running ("pro" versus gaming). This technology has needed one big name within the industry to guide developers, and looks like DX11 might be it. Very cool news.

Khronos group is going to the same direction. See http://www.khronos.org/news/press/r...g_initiativ e/ .

The spec has not been completed for Direc X 11, Microsoft is rumored to be wanting to add things like Displacement and maybe Subdivisional surfaces. Again this is rumor, but it is interesting. Direct X 11 could be a huge jump in technology that the industry would have to want to take advantage of. Other wise we could see tools shipping with game engines doing as much or more than conventional tools. Then we would be competing at the lower end with twelve year olds, oh boy!

Does this mean that the graphic cards, under DX11, could be used for 3d rendering calculations too?

Yes it means that. There are several instances where Game engines are used for Render mainly for interactive Architecture work.

the new shader technology seems confirmed.

"New compute shader technology will be available for developers to one day use a system's GPU as a parallel processor, and tessalation, which, according to the press release Big Download received via email, "blurs the line between super high quality pre-rendered scenes and scenes rendered in real-time," will also be available."

For GPU-rendering to FINALLY become a reality, it has to be supported by the single most powerful company in the computer world. The whole reason that this tech hasn't advanced beyond the most basic stages is simply because everyone and their mother seems to have their own way to doing it which is of course incompatible with everyone else's way of doing it - which makes all these techniques pointless because they have to be supported by mutliple software and hardware companies at the same time. What are the chances of competing software and hardware companies working together to get this technology going? Yeah, exact... zero to none. MS is one of the few companies that could pull this off.

yeah if only MS haters and Apple and Linux fangirls don't whine about it simply because Microsoft is doing something positive. Wait.. that won't happen, they'll still whine. Charge on MS!!!

Not quite a rumor it seems:

"Work with Microsoft on DX11 for supporting subdivision surface for higher degree of realism through graphics processor."

Tim Sweeney of Epic Games said in an iterview :

Quote:
Q. What are your feelings on displacement mapping?

A. Much ado is made about this feature, but ultimately displacement mapping is a form of geometry compression, and to realistically assets its benefits and drawbacks we must compare it to other geometry-compression schemes. In that regard, it’s a pretty crappy form of geometry compression! It requires a parameterization of the underlying surface (which itself imposes significant burdens on artists to create an artifact-minimizing mapping), and to hide the seams, and has a directional bias often unrelated to the underlying geometry.

Indeed, there will someday be a revolution in fine tessellation of objects with sub-pixel triangle rendering, but displacement mapping won’t be the magical feature that empowers it. More realistically, GPU makers talk about displacement mapping because it’s a thing they know how to easily fit into their existing pipeline. Much of the modern graphics pipeline is derived from such expedience rather than a thorough analysis of how we might maximize rendering detail with the minimum hardware cost.


http://www.evga.com/gaming/gaming_news/gn_100.asp

also he predicts the end of directx here:

Quote:
I think that DirectX 10 is the last DirectX graphics API that is truly relevant to developers. In the future, developers will tend to write their own renderers that will use both the CPU and the GPU - using graphics processor programming language rather than DirectX. I think we're going to get there pretty quickly.


and

Quote:
There are significant advantages in doing it yourself, avoiding all the graphics API calling and overhead. With a direct approach, we can use techniques that require wider frame buffer, things that DirectX just doesn't support. At Epic, we're using the GPU for general computation with pixel shaders. There is a lot we can do there, just by bypassing the graphics pipeline completely.


both above found here :
http://www.tgdaily.com/content/view/36410/118/

If you ak me they better improve 10 before going to 11 ... 10.1?

so since mr sweeney doesnt seem to have much faith in the longevity of directx, does that mean epic is working on their own directx competitor? UE4? please?

How many PC games are actually optimised for multi cores and 64 bit? Not to mention that even if this move is considered to be a positive one, it'll still have little impact if it's made exclusive to MS future OS like the current DX10 to Vista.

P_T: it could potentially be used on microsoft's next console as well.

Yeah Sonk, I was trying to be responsible with my post and then Microsoft officially announced some of thier specs, Oops. Serioulsy, though How fast is the 3D app companies and associated companies going to be able to jump on this. If a Game engine was shiping with all inclusive tools, they would be able to surpass certain 3D apps out of the gate.
The real time feedback and real time rendering would ceratinly be an enticing feature to make any artist want to take advantage of that.
The Software people in this field are really going to have to focus on delivering new software that takes advantage of all this power that sits in our computer and really only works when we render.
One thought that has always bugged me, how in the hell can Adobe not be right on top of this technology? They are the largest software company in the world that does not make an OS, you do not get that big and stay that big by staying slow and lethargic, or do you?

last thought, what do peolpe think, do you think when all these mulit Cores and multi GPUs and Direct X 11 are available that we could see some sort gaming app that could eat into this industry with much younger talent doing the driving? With real time this and Real time that, all they would have to do is record.
