Hacked DX10 for Windows Appears 336

Posted by CmdrTaco from the well-maybe-it-did-anyway dept.
Oddscurity writes "According to The Inquirer someone managed to write a wrapper allowing DirectX 10 applications to run on platforms other than Vista. The Alky Project claims to have reverse-engineered Geometry Shader code, allowing Windows games to run on Windows XP, MacOSX and Linux. The Inquirer is understandably cautious about these claims, urging readers to investigate the releases themselves to ascertain whether or not it's a hoax."

    If nothing else, this can be a call to others to create similar projects. If the Alky Project is real (which it is by all accounts so far), then even if it is shut down, their work will continue. If it can't meet it's goals in some way, then it's full promise will remain as a focus for the great need to NOT 'upgrade' to Windows Vista, drawing in a large number of developers. It is also the promise that applications made for DirectX 10 may live beyond their operating environment.

    This is very much a more direct refection of the same phenomenon that allows entire hardware systems to be emulated against the wishes of console, arcade and computer manufacturers.

    This is the start of the market's reaction to Vista, made manifest.

      Agreed.

      It's great to see that at least some people are fighting back against Microsoft's nasty move. If it's possible to implement DX10 on any other OS than Vista, it's just proof that M$ was just trying to force everyone else out of the gaming market. Of course, most of us already know about how slimy they are... but it's always nice to see a reminder.

    I downloaded it and everytime I start up a Direct X 10 tutorial it crashes out, the file sizes 400k also seem a little small.

    I'd also like to know how he implemented Vertexs and Indexs since in DirectX 10 you allocate one buffer and it can be any type but under DirectX 9 you have to choose the type of buffer when you create it. Copying all that stuff into memory so you can allocate the buffer in the DirectX 10 drive at render time is going to slow things down a hell of a lot.

    Still if it worked it would be very interesting for the wine project.

If DirectX was a separate project from the windows OS, then it would work on windows XP without us having to go hack it. There's no reason why DirectX 10 can't work on windows XP. It's just an artificial limitation that MS through in to get people to buy Vista. MS does this a lot, with IE, IIS, MS Office, DirectX, and many other tools. I don't see why people put up with it.

          Halo 2 is a perfect example of Microsoft making something Vista-only with no technical reason whatsoever. Halo 2 Vista uses DX9 for its graphics, sound, etc., and is artificially restricted to Windows Vista only because it is published by Microsoft Games and Halo 2 is a popular game in the console world.

          I've read that there actually are technical reasons why DX10 can't be trivially ported to Windows XP due to how it interacts with new driver models and other kernel-related things, but if Microsoft had separated the GUI from the kernel in the first place, this wouldn't be such a problem.

      I wouldn't necessarily list DirectX with the likes of the other projects. DirectX has always tried to be the best at compatibility, with redists and backwards compatibility for OSes that the rest of Microsoft had written off already (it's only recently that the SDK stopped supporting Windows 98, primarily due to lack of demand, since older SDKs still work). You could say that DX10 only supports Vista, but the truth of the matter is that only Vista supports DX10.

      It's fairly easy to adapt the API (as appears to have happened here) so that a certain class of applications will run on older hardware (and hence older operating systems), but those applications aren't interesting for DX10 right now, since DX9 already allows you to access the full feature set. As for running newer hardware on older operating systems, adding the required features to older operating systems would be a tremendous effort, since they go all the way up the stack, and would require changes to very old, very sensitive parts of the operating system.

      This is something that has possibly severe security implications for Microsoft, but even worse implications for others involved, since it adds yet another version of a very complicated driver from the hardware vendors, and a whole slew of compatibility testing across the board from hardware vendors to software vendors, all to support a shrinking segment of the market (people running new video cards on old OSes). So for everyone involved, it's makes much more sense to continue using DX9 on the applications that need to support older OSes, and consider using DX10 to exploit new hardware and new features that can't be implemented on DX9.

      I'm betting that there is another reason DX10 is only for Vista: performance. With DX9 and OpenGL, you can run games on XP and Vista, and compare them to see Vista is slower. With DX10 you can't compare anymore, so people forget Vista is slower.

      OpenGL already has extensions to support DirectX features, they were added by NVIDIA.

      Also, the entire OpenGL API is being redesigned from scratch (after 13 years of active service). The first version is currently named 'Longs Peak' and will have feature parity with the current version of OpenGL. The next version which is called 'Mount Evans', will build on Longs Peak, adding DirectX 10 features.

      From what I've seen of the new API, DirectX is in for a serious challenge (well, I hope anyway).

      More information about the new API can be found in the OpenGL newsletters [opengl.org].

      Yes, I paid. I'm one of very few so far, apparently. At the time, I thought their focus was to make Windows games run natively on Linux, 1 at a time. (Meaning the game will work well and they won't move on to the next until it does.) The very next week, their focus is shifted to DX10. 'Cool,' I thought, thinking it was DX10 on Linux. I now see it's on Windows XP... Bleh. No answer from them on if they plan to make it work on Linux also.

      $50 wasted.

      See, I've -got- the money to spend on the hardware and the OS and all the upgrades for the next few years. That isn't the issue. I just want games to work on an OS with good moral character. Or at least neutral. I'd settle for 'not completely shady.' But nooooo.

      By the way, their Linux demo that is only for paying people... It doesn't work on my system. There's no sound, and it crashes after the menu. They spent a couple weeks looking at it, but their final answer was 'We can't reproduce this bug' and 'we need to focus our effort on the product.' While I agree that's probably the right attitude at some point... When you've only got a very very few paying customers, you make ALL of them very happy so they'll bring in other paying customers.

    I know everybody wants to believe that Microsoft arbitrarily decided that DX10 would be Vista only so they could "force" people into buying the OS, but, as usual, it's a tiny bit more complex than that.

    DX10 relies heavily on graphics card memory virtualization. The new Windows Display Driver Model, WDDM [msdn.com], introduces this feature. In order to accomplish this, it required a lot of low level kernel changes. So many, in fact, that back-porting it to XP would basically make XP's kernel into Vista's kernel.

    There comes a point where you just have to say that a particular feature is only available in Vista. DX10 fits that bill.
