Hi, I have a few questions about upcoming games; Mainly i want to know which games are gonna use DX10, the only game i know who will is Crysis... Also, When the game S.T.A.L.K.E.R. releases it comes with DX9.1, will this version fully work with DX9.0 cards?? Thanks.

Yes, it will work with DirectX 9c cards. Though it should work just fine, a DX9c card may not have the level of performance or detail that a DX9.1 card would have in a game that fully supports it. I don't know much about DX9.1 because it was supposed to be released four years ago and has kept getting pushed back (or turning into DX9 revisions) so I'm not sure exactly what new features it entails. But just like DX7 cards can play Half-Life 2 (albeit at lower detail), which is a DX9c game, the latest DX9.c cards still have a lot of life in them. I wish my lawn was emo so it would cut itself.
