DX11 Tested Against DX9 With Dirt 2 Demo 201

MojoKid writes "The PC demo for Codemasters' upcoming DirectX 11 racing title, Dirt 2, has just hit the web and is available for download. Dirt 2 is a highly-anticipated racing sim that also happens to feature leading-edge graphic effects. In addition to a DirectX 9 code path, Dirt 2 also utilizes a number of DirectX 11 features, like hardware-tessellated dynamic water, an animated crowd and dynamic cloth effects, in addition to DirectCompute 11-accelerated high-definition ambient occlusion (HADO), full floating-point high dynamic range (HDR) lighting, and full-screen resolution post processing. Performance-wise, DX11 didn't take its toll as much as you'd expect this early on in its adoption cycle." Bit-tech also took a look at the graphical differences, arriving at this conclusion: "You'd need a seriously keen eye and brown paper envelope full of cash from one of the creators of Dirt 2 to notice any real difference between textures in the two versions of DirectX."

    I Personally view DX11 as I do sonys push from DVD to blueray. Sure blueray has some nice features but I'm still enjoying my DVDs, and I don't really need uncompressed audio tracks for every language on my disks. Same thing with DX11, I've not even properly gotten set with many DX10 games and now they are pushing DX11 (well pushing as in mostly tech demos) and I've not even got much dust on my latest graphics card. I'll upgrade in a few years, perhaps when I see DX9 vanish, or at least become increasingly uncommon.

      It's another to compare the gigantic difference in picture quality between 1080p/720p and craptacular 480p (at most)

      The difference between high def and standard is pretty darn immediate and obvious for new content such as TV shows that were made using the right digital cameras. Film, not so much, because the darn camera and lenses in movies is often set to blur hard edges and details, and of course is a craptacular 24fps.

        On a DVD, if something's out of focus, it could be because of the cinematography, or it could be because the DVD doesn't have enough bits. On a bluray, if something's out of focus, it's probably because the director of photography intended it to be out of focus.
        Water looks a bit more realistic. Animation looks a bit sharper.

        On a smaller screen, these are all subtleties, and don't jump out at the viewer unless edge enhancement is added-- which tends to bother viewers with larger screens. Too much processing can also make skin look like plastic.

Sure, high definition is better, but it costs sometimes twice as much for the HD version a the moment. The GP didn't say he couldn't tell the difference, just that he didn't see the need for an increase in quality.
        • Sure, sometimes good enough is good enough for most. Then there are some who care about quality and are willing to pay more for it. I happen to enjoy watching films more when they are on Blu Ray, and the higher quality image and sound further immerse me into the experience. If you don't happen to find the difference worth the cost, that's fine, but I see no reason to complain. Blu Ray is coexisting quite nicely with DVD at the moment, and I don't see anyone shoving the upgrade down your throat.

        The fact that you don't remember the graphics being ugly means that they were, in fact, pretty. Or at least, the artists and developers successfully collaborated to provide a game world [predominantly] without offensive glitches. When it comes right down to it, that is a massively difficult task, and consists of a truly massive and complex work of absolute art. Not that I've actually played any of those games. I'm getting ready to try out Lost Planet on the 360.

        And doesn't the X360 use DX9? Considering how many PC games are nothing but shitty X360 ports anymore DX11 will probably be waiting until the x720 before getting adopted.

    • Personally I see DX11 just like BluRay as well: What good is better graphics if all you get is to see better how much the content sucks?

      Movies without scripts don't get better just with more eye candy. Likewise, games with no replay value don't get more interesting with more particle effects.

      • by yoyhed ( 651244 )
        Exactly. I'd like to note that all of Valve's games are still DX9, and they still rule, and they also look pretty damn nice in my opinion.
      • No country for old men had a fine script. It looks pretty spectacular on bluray.

    • The size of your TV makes a huge difference. My first HDTV ever was a 32" TV, and the difference between HD and standard TV didn't seem that great. Then I got a 56" TV, and the differences were jarring. I can't stand to watch normal TV now.

      Likewise, the difference in quality with BluRay is also suddenly more prevalent on a larger screen.

      Most of the "important" features of Direct3D 11 will be exposed immediately as OpenGL extensions.
      The next version of OpenGL will officially support those features.
      As usual, it will be a nightmare to take advantage of those features without requiring their presence. (GLEW and GLEE help only so much.)
      If there are any features of Direct3D that would require architectural changes to OpenGL, they won't appear until the next major version, at the earliest. I'd be surprised if virtualization of texture memory were supported soon, but I'm not really expert in these developments. (For all I know, it is already supported...)

      In summary, OpenGL will remain competitive with Direct3D with the usual caveats.

      • Most of the "important" features of Direct3D 11 will be exposed immediately as OpenGL extensions.

        Well, given the fact that the most important feature of DirectX 11 isn't Direct3D, but in fact is DirectCompute, OpenCL would be a better suited equivalent.

        And OpenCL integrates nicely with OpenGL, just like DirectCompute with Direct3D.

        But beside a few simulation eye candy like water surface or debris during an explosion, it won't cause much difference in games (because otherwise the physics would influence too much on the game play).
        That is, until monstrous power hogs like Crysis 3 and Windows 8 are out. T

      Not even sure if I knew there was a DirectX 11

      Well, of course.
      Most of the new features of DX 11 have nothing to do with graphics. There are few addition to Direct*3D* and biggest new stuff of DX11 is Direct*Compute*.
      It's for general purpose computing on GPU.

      Therefore it's no surprise that no player and game company gives a damn about it.
      It has few advantage to offer on most current games.
      It also explains why the testers almost didn't see any *visual* difference between the DX9 and DX11 versions. (It's not the same as between DX9 and DX10 - where most differences were on the graphic side - Direct3D - and thus translated into more eye candy).

      DX11 is not used for the visuals. It is used for the computations going under the hood. It will be useful for physics simulations, etc.
      The main problem in such situations - just like a few years ago with the PhysX accelerator - is that you can't have different level physics support that won't affect the gameplay.
      With difference of graphics capability, you can just have difference in detail level : one configuration will look prettier than the other, but the game will always play the same.
      But you can't have more-or-less realistic physics, because the game won't play the same if the objects don't react the same based on the level of physics simulation. Therefore, the gameplay use the same simulation no-matter what the configuration is (the same rigid body physics for all player-driveable vehicles), and GPGPU (CUDA, OpenCL or in this situation DirectCompute) will only be used for a few small details - water surface, cloth simulation, debris displayed on screen during an explosion animation, perhaps ragdoll physics for NPC death (in games where it doesn't matter where the body lands).

      Thus differences are virtually invisible on screen shots. Its only while playing that some of the players will say : "Hey look, the monster fell in a funny way down the stairs !"

      Does anyone know how OpenGL compares to direct3d 11?

      Given the above, the most correct would be to compare Open*CL* to DirectX11.

      And OpenCL does very well. It looks like a genericised version of CUDA, with a slightly lower level API on the host setup side (the same level of verbosity as OpenGL).
      Also, OpenCL integrates well with OpenGL (just like DiectCompute integrates well with Direct3D)

      Last but not least, OpenCL will be supported much more widely in its target market (Scientific computing) having implementation for most OSes (including Linux and MacOS X), having support from major hardware producers (ATI, Nvidia, Intel) including embed ones (ImaginationTech. PowerVR, ARM, etc.), and even having open-source implementation (Gallium3D framework for the next gen Mesa3D).

      Whereas DXCompute is only available in Windows 7 and probably soon on the current or on the next XBox.

      In conclusion :
      In most case, game developers wont bother (except in some simulator requiring as much realism as possible and thus advanced physics support).
      They'll rely on 3rd party middle ware for physics (like Havok).

      And middle-ware makers will probably target several platforms anyway, in order to be interesting for non-microsoft consoles too.

Even at that, the difference between High and Very High is not earth-shattering. The Internet quickly figured out how to enable all of the Very High graphics setting for DX9 through .INI tweaks, even before Crysis was on store shelves.
