AMD Previews DirectX 11 Gaming Performance 103

An anonymous reader writes "AMD invited 100 people up to their private suite in the hotel that Quakecon 2009 is being hosted at for a first look at gaming on one of their upcoming DirectX 11 graphics cards. This card has not been officially named yet, but it has the internal code name of 'Evergreen,' and was first shown to the media back at Computex over in Taiwan earlier this year. The guys from Legit Reviews were shown two different systems running DX11 hardware. One system was set up running a bunch of DX11 SDKs and the other was running a demo for the upcoming shooter Wolfenstein. The video card appears to be on schedule for its launch next month."

      Bigger problem: Probably runs worse than directx9 with it's only "advantages" being one or two minor shader effects (geometry shaders...) and a lot of games that arbitrarily lock things to Dx11 mode when they could run just fine in dx9 mode.

        You are dead wrong. Direct3D 11 and Shader Model 5.0 is quite the step up from Direct3D 9 and SM 3.0. If you were a graphics developer you would know this. From Wikipedia:
        • Tessellation to increase at runtime the number of visible polygons from a low detail polygonal model.
        • Multithreaded rendering to render to the same Direct3D device object from different threads for multi core CPUs.
        • Compute shaders which exposes the shader pipeline for non-graphical tasks such as stream processing and physics acceleration, similar in spirit to what NVIDIA CUDA achieves, and HLSL Shader Model 5 among others.

        It also has a lot of awesome smaller features that make doing what are known as deferred shading/lighting pipelines more feasible. This is a good thing because it simplifies the amount of work needed in implementing game's material system while offering great performance at the cost of more GPU memory being used.

            Most game developers are skipping Direct3D 10 because it's explicitly tied to Vista and it has poor market share compared to Windows XP/Direct3D 9.0c. The hope is that most current gamers on Windows XP will eventually move to Windows 7, and that Direct3D 11 enjoys the same long life span as Direct3D 9.0, ending up in the console from Microsoft.
        • Certainly, there are a few features that speed rendering up, while making it look better.

          But those same features were probably available on older cards - just not exposed in the API. I saw an OpenGL Parallax Occlusion demo years back, running on a GeForce 6 or 7. (Can't recall which)

          HDAO looks nice, but the performance hit is massive. I just know there's going to be a few games that force it on, completely tanking your framerate for a few shadows. :P

          And yes, framerate dropping to 10% is completely tanking.

      • From my viewpoint the changes made in recent releases of DirectX are no small matter, to label such things as "minor shader effects" shows your ignorance of the subject. The DirectX SDK [microsoft.com] contains wonderful documentation if you are so inclined to learn.

        I'm not arguing for or against Microsoft platforms but the fact remains DirectX is currently the de facto standard in creating games. And even though it's a COM based technology, it's still kinda fun to play with.

      If you do not have the hardware to support Windows 7 then don't upgrade. If your graphics card is the only thing holding you back then take a stroll over to Newegg [newegg.com] and start upgrading.

      Complaining about hardware that was designed for Windows XP not working in Vista/Win7 is really akin to complaining about hardware that worked fine in Win95/98/ME not working or working well in XP.

    Well I read TFA and besides the new capabilities of DirectX 11 (which look nice, but not exactly earth-shattering to me and also will need some time to get implemented into games anyway), what I found interesting was what ATI actually did with the display output connectors.

    The demo system they set up had one of those new DirectX 11 cards and that card is a dual-slot solution as all the highend graphics cards are now. But ATI did use the space from those two slots quite nicely by including dual DVI ports AND a HDMI AND a DisplayPort connector meaning you have all the different types of digital display connectors available on a single card, which would be a first, I think.

    No word yet whether you can use all four ports simultaneously, but if you could, it looks like a nice new way of hooking up multiple displays :)

      • See, this is what I don't get - why does everyone think HDMI is so awesome? It's just DVI with a couple extra pins for audio. It's not inherently higher-quality; does it have a sufficiently higher bandwidth capacity than DVI + TOSLINK that it makes an impact in real-world environments (24fps 1080p video/5.1 surround sound)? And how is having your video card double as a sound card a good idea? Isn't that just asking for aural interference from the video components?

          First point: HDMI is all-digital, so you don't get "aural interference from the video components". It's actually a pretty cool feature of the current batch of HD 4xx0 cards that you can run the output of an HTPC on one cable.

          Second point: HDMI, in the later revisions of the spec (1.3+ or so), actually does have improved features over DVI, like deeper color support, and higher bandwidth to support higher resolution displays. (It also supports 7.1 sound, not merely 5.1. Not that you actually need any of thi

    Since most you other fucks just make some sort of quip with no facts, (yeah yeah, i know it slashdot) here is the wikipedia entry for DX11.

    "Microsoft unveiled Direct3D 11 at the Gamefest 08 event in Seattle, with the major scheduled features including GPGPU support, tessellation[11][12] support, and improved multi-threading support to assist video game developers in developing games that better utilize multi-core processors.[13] Direct3D 11 will run on Windows Vista, Windows 7, and all future Windows operating systems. Parts of the new API such as multi-threaded resource handling can be supported on Direct3D 9/10/10.1-class hardware. Hardware tessellation and Shader Model 5.0 will require Direct3D 11 supporting hardware.[14] Microsoft has since released the Direct3D 11 Technical Preview.[15] Direct3D 11 is a strict superset of Direct3D 10.1 - all hardware and API features of version 10.1 are retained, and new features are added only when necessary for exposing new functionality. Microsoft have stated that Direct3D 11 is scheduled to be released to manufacturing in July 2009,[16] with the retail release coming in October '09"

    Seems pretty big to me. The thing I see being the biggest is the work on improving multithreading/multicore support, and the whole GPGPU thing. Not to mention that the API will be very compatiable with older cards (read: no real need to upgrade cards just yet)

        One of OpenGL's advantages was that the code would work on a number of platforms. Originally on IRIX, IBM licensed it so it worked on AIX machines. Then it moved to other platforms, surpassing 3DFX's Glide interface. OpenGL is still being worked on, 3.2 was released not so long ago.

        Direct X11 offers the GPGPU support, but it also offers multithreading (some games chew CPU cores up like they are going out of style, so having threads split up among multiple cores will help performance)

      They do support OpenGL, in fact ATI's Direct3D 11 cards will support the latest version, OpenGL 3.2. However, it should be noted that the OpenGL 3.2 feature set is the same as Direct3D 10, which doesn't really bring anything new to the table. Direct3D 11 is where all of the new features are.

      DX10 was a flop because Vista was a flop. If MS let users of XP grab DX10, DX10 would have caught on in games, but it was Vista-only and no game makers were about to (or are about to) invest a ton of money in a game that's either Vista-only or in the work to make a DX9 game actually make full use of DX10 features. DX10 just was irrelevant because a great majority of the market wasn't able to use it.

      • Sweet, random Flamebait moderation! Some kind of die-hard DX10 / Vista enthusiast take offense?

    • DX10 was more to alter the hardware removing variation. DX10 had little to do with implementing how the user sees the game visually and more to do with how the cards are kept up to standard and the games are programmed. Honestly, I feel that DX11 will be somewhat that way as well with the gpgpu support, threads, and so on.

  • Neat! The idea of drawing a 2d picture and then having an engine that auto adds wireframe and all that fun stuff seems to remove a lot of work for the developer.

    I honestly thought dx11 to be more of a dx10 where most of the alterations would not be noticed by the gamer (like threading) so I'm glad they are adding something visual to help people want to push to use dx11.
