Betanews has already had a bash at reviewing it, which you can find on the same page as above.
Be careful! You cannot un-install this without re-installing Windows, and with XP this might not be as easy it could be. You could always roll back to a version of XP without DirectX 9 -- in face we've had to do this following some "critical updates" earlier this month. Sheesh.
Also remember that few hardware products support DirectX 9, yet.
A source close to Microsoft's plans said that the download is really still a beta release candidate and not even RC1, and there will be more releases in the coming months.
That means, he said, that by then ATI will not have the only card that supports DX9 and that the driver support for this release is very very minimal.
Further, there does not yet seem to be a public SDK. Apparently Phil Taylor, in charge of the DirectX 9 programme at Microsoft recently left.
He said: "Anyone who uses this except on a spare machine is nuts." * µ
* JUST A NOTE This last quote is not attributed to Phil Taylor -- apologies if that seems the case from the
juxtaposition of the quote to the previous paragraph -- but to the previous "source". (MM)
