Havent heard that. And if it were true i personally wouldn't do it...
Why are we talking DX10? DX11 is out now.
Are you talking about the Alky project?DX10 is available on XP, just install it.
Yeah the link to the Alky project is here: http://www.technospot.net/blogs/download-directx-10-for-windows-xp-from-alky-project/
Why you would stick with XP is a wonder to me now though?
There is quite a few differences other than tha.
