That dx10 thing, and company is probably fake.
BTW, if it was true, you wouldn't need dx10 drivers.
The whole concept of it is to convert dx10 to run on dx9.
Most dx10 games have embedded activation drm that only work in Vista, so dx10 isn't the only thing you need to run them.
Anyway, to see how much vista sucks, read this article:

The true dx10 conversion is really OpenGL.
Since OpenGL can run, and be updated, on any OS, all you need is an OpenGL capable card and a game that uses the API.
Although support in that would be dependent on the driver.
Wine may someday support dx10, but it won't happen anytime soon, and those guys are way more professional than these alky guys, so that should tell you that this dx10 emulator is a scam.
Another thing is that Halo2 is not dx10, its dx9 and it's already been cracked for XP.
You're only fooling yourself believing those scammers.
