In order to use DX10+ you must be using Windows Vista - Windows 7.
Sorry to be the bearer of bad news.

On a brighter note, Windows 7 is ROCK SOLID!

I've run both Vista 64 and Win7 64 (Ultimate for both) and Windows 7 is much more stable and takes up a lot less overhead (memory wise) than Vista did. If you're going to have to upgrade for the new DX, then upgrade to Win 7.

Forgive me for taking this thread just a bit sideways.I am a Windows XP user,& no PC whiz...is the download & instal of Windows 7 a difficult deal ( I mean more than just parting with the purchase price...?)
Can I do it without a degree in Computer Science? :roll:
