DirectX 12 Ultimate is an Attempt To 'Future-Proof' Graphics Hardware (pcgamer.com) 56

Posted by msmash from the shape-of-things-to-come dept.
A new DirectX badge is going to start showing up on graphics hardware: It's called DirectX 12 Ultimate, and it denotes support for "ALL next generation graphics hardware features," Microsoft announced today. From a report: DirectX is a collection of application programming languages (APIs) that developers use to communicate with your hardware. You can think of it like a conduit between software (especially games) and hardware. Up until now, DX12 was the latest version, supported in Windows 10 (and also in Windows 7 for some games). Now that distinction belongs to DX12 Ultimate. It's not an overhaul of the API, but a culmination of the latest technologies bundled into one. This notably includes DirectX Raytracing (DXR), variable rate shading (VRS), mesh shaders, and sampler feedback.

One of the reasons Microsoft is doing this is to unify experiences across the PC and its upcoming Xbox Series X, which will launch November 26, 2020 (Thanksgiving Day). "These features represent many years of innovation from Microsoft and our partners in the hardware industry. DX12 Ultimate brings them all together in one common bundle, providing developers with a single key to unlock next generation graphics on PC and Xbox Series X," Microsoft explains. The main benefit for gamers is knowing, at a glance, if the graphics card they are about to buy supports all the latest features. Spotting the DX12 Ultimate badge is the key, and I suspect hardware makers will be quick to promote it. Related to that, Microsoft is pitching this as a way of ensuring "future-proof" feature support. There's no such thing as future proofing, of course, but DX12 Ultimate should remain relevant for at least the next couple of years.

    If DirectX is the same as OpenGL, and new commands are rolled out to PC and XBox at the same time... is there any difference left?

      DX12 and Vulkan are virtually the same feature wise at this point and have shader translation software so you can write in one language and use it in the other for facilitating porting... dunno why you think OpenGL is the same.

      Currently there is Zero reason anyone should be using DX12.. other than they love vendor lock in.

        That lovely vendor lock-in that lets your development automatically access a market of 50million additional devices (xbox)? Based on available customer figures alone it would seem there's zero reason to develop in Vulcan.

        It's like saying you shouldn't develop for iOS because of vendor locking. Remember developers don't develop for shits and giggles. They develop for customers, and there's a reason why basically every game on the market is DirectX with Vulcan as an optional extra.

      Vulkan is functionally equivalent to D3D12. OpenGL is not.

      • Correct me if I'm wrong but isn't Vulkan just a subset of OpenGL streamlined/optimized for mobile and gaming, which would be why it was called "OpenGL ES" until it was renamed?

        • > Vulkan just a subset of OpenGL streamlined/optimized for mobile and gaming

          No. You are thinking of OpenGL ES -- the ES stands for Embedded Systems.

          At the time OEM phones weren't going to use M$'s proprietary Direct3D so that left OpenGL as the only cross-platform API to consider. Unfortunately standard OpenGL is bloated so they came up with a modern, slim version and called that OpenGL ES.

        • Vulkan is more like a superset of OpenGL/CL, with more low-level hardware access. I have seen plans to write OpenGL as a compatibility layer above Vulkan, so that GPU vendors need not publish separate OpenGL drivers, only Vulkan.

    • Yes, the difference is that Microsoft owns one of them outright and is intent on making the others irrelevant.

  • "There's no such thing as future proofing, of course"

    OpenGL works very well towards doing this by allowing extensions that are non-standard, thus ensuring that you can (with some code and enough GPU power) support the latest graphical hoo-hahs.

    • OpenGL works very well towards doing this by allowing extensions that are non-standard

      I'd ask what fresh hell is this, except it really sounds like the same old, stale DLL and driver hell. I remember fondly the time wasted searching for obscure drivers or combinations thereof that would somehow coax some games to run on my vanilla graphics card. Did I say fondly? I meant with loathing.

      You mean like the fractured garbage that is Xbox console naming? I await DirectX 12 One or DirectX 12 Series Ultimate in a few years.

    Because if you want to develop without MS lock-in, that's what it's gonna be.

    Sorry, MS, you're not monopoly anymore. Mo hard feelings.

    • And even on Windows, I think there's still a majority of gamers using Windows 7, thus unable to have DX12.

      • A majority? Really?

        • I could be behind the times, but that was my understanding not too long ago. No one really likes Windows 10, not even gamers.

          • A lot don't but there isn't much choice these days.

            also FWIW Steam says 80.5% on Win10 and 13% on Win7. I'd bet GOG etc have a higher percentage on Win7.

            • Ha, I'm more leaning towards GoG. And since they have older games that's where I hear the "i upgraded and now my games don't work!" complaints. Whereas Steam feels oriented to brand new games much more often.

          • I could be behind the times, but that was my understanding not too long ago. No one really likes Windows 10, not even gamers.

            No, that was Windows 8.

            • I'm using 8.1 :-) 8.0 was a bit annoying but it's ok now.

              (I may upgrade since my mom needs to upgrade away from Windows 7, and I need the same OS version so I can help her.)

      • And even on Windows, I think there's still a majority of gamers using Windows 7, thus unable to have DX12.

        Why would a majority of gamers stick to a system that is slower, doesn't support features of their gaming hardware, and limits their access to games by locking out a few stores which are Windows 10 only?

        Your "majority" is wishful thinking. In fact back when people were shitting on Windows 8 and 10 for it's flaky and generally shitty experience it was the gamers that were happily migrating to Windows 10.

        • Then this is news to me from last I checked. I remember games bitching aobut W10, lots of concern about games that stopped working, and so forth. W7 is not slower, and the few new features in DX12 weren't enough to entice people to uproot and switch to a new OS (I hate to say "upgrade" in this context). Are there a significant number of important games that are W10 only?

          • Are there a significant number of important games that are W10 only?

            Indirectly, perhaps. I recently discovered that if you want to use any recent Intel chipsets you have to use W10 because there are no drivers for W7.

      Aren't they? DirectX provides automatic support for the PC and Xbox. Vulcan provides support for ... PC. Which one would you code in if you were a game studio attempting to maximise your audience. If you said Vulcan I hope you don't make any strategic decisions at your work.

      There's a reason basically every major game is written in DirectX and the odd one has Vulcan support bolted on the back.

        Found the amateur programmer who never actually ported games to other platforms and compilers to:

        a) find bugs, and
        b) take advantage of new markets and platforms.

        Tell me, how is that DX working out for you on PS5 or Switch? Oh wait, it's not available.

        • Tell me, how is that DX working out for you on PS5 or Switch?

          Tell me what colour jacket your strawman is wearing. You're the only one who mentioned PS5 or Switch. Finding bugs in code ported from Windows to Xbox which is written in DirectX is absolutely trivial compared to doing a PS4 of Switch port.

          Your option isn't to abandon DirectX completely. It's only to abandon 50 million xbox customers. You can either code for DirectX + PS4 + Switch, Or you can code for PC + xbox + PS4 + Switch, the latter requiring far more effort and cost for the same result.

    The disadvantages to using DX12 over Vulkan should be pretty obvious I'd think, the other comments go into them multiple times. Are there any advantages to using DX12 instead? Speaking to like functional stuff that maybe DX12 does better. I'm just curious, I'm sure MS has put a decent amount of money and time into developing it, it seems like if it was universally inferior to Vulkan, people would just never use it.
