    DirectX does not seem a good standard for the industry to follow. DX9 came out how long ago? It seems as if 3D technology advances have slowed down. Yes there have been updates to DX9, but I don't really remember anything that was exciting. Yes, there has been talk about DX10 and the changes it would bring, but now it's known that it's Vista only. That's why it has taken so long. So the industry is waiting for Vista to finally have implementation of their new graphics features? Sounds like a bad move. What if MS delays Vista? What then? Are the graphic chip makers gonna sit and wait? What we need is an actual open industry standard. Bring back OpenGL so we can make improvements as they come, and not having to wait for Microsoft to lead it where they feel they can control it to make money, and continue locking out other platforms.

        "I think DirectX sucks for a variety of reasons but the truth of the matter is there are no real video card features DX9 doesn't currently implement. Neither Nvidia or ATI have yet to release a card with the new feature sets in DX10."

        Well, you can run games using older versions of DirectX in Vista, so how exactly is this a problem. DirectX 10 isn't out yet and you're complaining about the lack of DX10 cards? ATI and nVidia are on development cycles and they would obviously not include DX10 support on current graphics cards, simply because DX10 wasn't mature when today's architecture was under development. I am very sure both nVidia and ATI are dying to get DX10 cards out as soon as Vista is out, since selling the first fully Vista compatible cards is a huge thing. You can't expect today's tech to support something that isn't even released yet. That doesn't make sense.

        Even then it makes me wonder what the point is. When games like WoW get all the headlines using technology that barely require DX8. Maybe if you are into FPS games this will matter but for everyone else the featureset you are calling dated far outpaced the software that runs on it years ago.

        Excuse me, but are you even aware of how many of today's games rely heavily on DX9 technology? You are also saying that games like World of WarCraft barely use any DX9 tech. Do you have any documentation on that? Also, what is "games like WoW"? In fact, many "games like WoW" today use pixel shaders and therefore require DX9. Yes, FPS games are clearly taking advantage of the latest technology, but the simple reason is that realism is far more important in such games than, say, strategy games. But on the other hand, there are so many types of FPS titles. We have racing games, action games, MMORPG and even adventure games. World of WarCraft may not be the most graphically advanced game, but this is for three main reasons: it's huge and would simply require too many gigs of space if it was more complex than it already is. Blizzard is also targeting a larger mass who isn't constantly upgrading its hardware as much as some other groups do. Last but not least, have you ever thought of how much more time and money Blizzard would have to invest to include the latest technology with the highest level of detail?

        I'm pretty skeptical of how OpenGL will survive in games now that Carmack has sold out. It's a bleak future for those of us gamers who want to someday drop Windows and use a real OS.

        You know, Carmack has all the money in the world already. I doubt he would kiss Microsoft's ass if OpenGL was more promising than DirectX. After all, as a DirectX developer, you also get to release your games for the Xbox without too much hazzle, which is only one of many reasons why DirectX is more successful. OpenGL is in no way a poor API, but most developers currently support DirectX because it looks more promising than OpenGL. Also, Carmack was one of the main donators to the OpenGL foundation. Why would he fund a project like this and then kill it? I'm sure it was painful but as Carmack is always set on developing the latest in technology, he is also looking at the two API:s individually before deciding what to go for.
        • As the other poster already pointed out, DX8 is the first version that supported shaders. Also, using more advanced shaders do not grow the size of the game by "too many gigs of space", shaders are quite tiny, usually under a few kbytes in size. In fact, if a game uses some of the more advanced procedural shaders that become a realistic possibility with DX10, the size of the game will decrease as some of the art is generated at runtime instead of being handcrafted and stored in the game data.

    Just by reading this article title, it may seem rather like we're getting ahead of ourselves here - After all, we still have another handful of DirectX 9 boards to come from ATI, never mind being a fair few months away from the launch of Windows Vista, and with it the latest iteration of the DirectX API, DirectX 10.

    Nonetheless, despite all this, DirectX 10 is likely to see a number of point revisions during its lifespan and the first of these, imaginatively titled DirectX 10.1, will be the first of these. It may surprise some of you reading this, but the features which will be added by DirectX 10.1 have already been decided upon and information made available about them, so in this article we'll be taking a look through what we can expect to see in DirectX 10.1 compliant hardware.

    I would imagine this goes without saying, but before tackling this article I'd well and truly recommend beginning by reading our look at what DirectX 10 has to offer in our article entitled "ATI on the possibilities of DirectX 10" to get yourself up to speed on everything that this major inflection point in 3D graphics rendering entails, from geometry shaders through to (more importantly for this article) the WDDM driver model. So, if you feel that you know all you need to know about DirectX 10, let's move onwards to the future world of DirectX 10.1.

    Introduction

    Before we begin outright, we should remind ourselves briefly as to exactly why the API will be seeing point releases as of DirectX 10. The main reason for this move is the removal of cap (or capability) bits in the API. In the past, cap bits allowed for graphics vendors to basically pick and choose what features their hardware would support (albeit within some fairly strict guidelines to ensure compliancy to particular DirectX and Shader Model revisions). Although this left the likes of NVIDIA and ATI with plenty of room to develop and tout features that the other didn't have, it also had the side effect of creating development Hell for any game developers working on titles, leaving them to sort through a myriad of cap bits for different GPUs and configurations to ensure that they were supporting the right features for the right boards - More often than not, this simply meant that advanced features that only one graphics vendor supported were left out of the vast majority of titles altogether (Truform anyone?). The removal of this labyrinth was one of the main things developers were screaming out for when it came to discussing what was required of DirectX 10, and so it came to pass.

    Of course, this removal of cap bits had to be offset against the ever changing and progressing world of GPU development, so the graphics vendors still needed a way to push the technology forward and allow new technologies to find their way into games. Thus, DirectX 10 will be seeing point releases, one of the main facets of which will be to facilitate the inclusion of new funtionality for compliant graphics hardware to make use of. This makes life easier both for developers (who can target DirectX 10, 10.1 etc rather than individual features) and consumers - How do you explain to the man on the street that yes, a Radeon X800 and GeForce 6800 are both DirectX 9 parts, but both support different Shader Models in their respective architectures. It isn't much fun, trust me. As DirectX 10 and its point releases will also have very little in the way of features that are only optional in the API, buying a graphics board compliant with a particular DirectX 10 version will ensure that it does everything it needs to do to satisfy game titles that use that level of technology. No more Vertex Texture Fetch-esque confusions this time around then.

    The other question to answer (or not answer, such is the way these things work) before we start is - When will DirectX 10.1 be released? From what we've heard thus far, it appears that it may well become available not all that long after DirectX 10 itself. What isn't so likely however, is that we'll be seeing DirectX 10.1

    If I were a DX developer I'd be more interested in playing "ubiquitous developer" than "Windows Sock Puppet".

    • It's just like the rest of Win32. There is nothing magical. But as you implement it new versions will come out and you'll be in constant catch-up. On top of that, DirectX is used for games so you need to have it perform well. This combination makes it hard. CodeWeavers and Cedega are both trying.
      • DirectX for the most part depends on a decent API to the GPU and nothing more. The networking/sound/etc can all be handled by portable APIs [e.g. on top of BSD sockets, ALSA sound, etc].

        The real reason you don't see DX for Linux or BSD [or MacOS] is that they use it to prop up Windows. E.g. "Experience the coolness of DX games, as only brought to you by Windows." The problem is that DX is a viable technology [just like Visual Studio and Office] that in any other market would not be tied to the OS.

    • Maybe lack of driver support? Then again, even though its feature set moves like molasses and causes developers extension headaches, I still prefer the OpenGL API over DirectX9 even though I use C++ a lot more than C. DX10 is supposed to have an entirely different API so maybe I'll give it another chance.

      If someone did make an Open Source implementation, I wonder if Microsoft would pounce with patents. I feel like they only tolerate Cedega because it's far from perfect and in a way helps put out a mess

    • The license..it's the intellectual property of Microsoft and they can lock developers into writing games for windows by keeping the API's on windows. Microsoft as never licensed DirectX to ANYBODY and have no plans to ever do so.

      Same thing with the the rest of the Windows API. It could be implemented on Mac/LINUX (Wine tries to do it by reverse engineering), but it does not help them (Microsoft). It keeps people from running windows apps on platforms other than Microsoft Windows.
    • "Just like Visual Studio and Office it's yet another thing that props up Windows."

      Clearly a workable strategy. End users don't care one jot about the OS, but what they can do with it, and Microsoft have been very good at pouncing on those opportunities and communicating what you can do with Windows.

      The fact is, games will probably drive Vista adoption more than any other factor save factory pre-installs. We proabaly won't see much requiring DX10 for a year or more, but that is because most big games take 1-3 years to develop so that's about the earliest that we'll see stuff.

      This may cause game manufacturers to change tactics since OpenGL is supported on ALL OS's.

      That fact has always been true, and it hasn't made much of a difference so far, even back when OpenGL and DirectX were much closer in abilities (without needing extensions and such).
