Hacked DX10 for Windows Appears

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."

      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.
