Will DirectX 10 become available for Windows XP ? If not, why ?

DirectX10 has been written to be an integral part of Vista, not a bolt on
for other OS. In the past the purpose of directx was as a quicker router
to hardware than the desktop. Vista is designed to be more efficient at
the low level, so instead of bypassing the low level, direct10 works
through it.


DirectX 10 eliminates all the legacy support for previous DirectX versions.
This is a great thing since they can concentrate on new and future
technologies. DirectX 9.0m will allow for backwards compatability.

That being said, there is really no reason DirectX 10 can't work on XP since
the foundation between the two OS's is nearly identical. Vista is nothing
more than a glorified XP with a fancy front end. Sure there may be some
enhancements, but probably nothing that couldn't be done in XP and as
efficiently.

The netzines are calling it an incremental upgrade to XP and a rather
small one at that, but that gives no guarantee than any of the stuff
designed to work with vista will work with XP and the fact is it
probably won't. The big difference with Vista is the layer wrapped
around the kernel that takes care of WDM and DRM. I would assume that
DX 10 is designed to work through and with this. It might be possible
that it could be made to work with XP but I doubt it.

Vista will work with HDMI and recognized devices. If you play DRM
enabled content that says it is premium Vista will still play it IF
everything in the stream is, for lack of a better term, HDMI approved
or rater IDd and vista is getting rather picky about system changes
too according to Computer World.
