If I am not mistaken, the upcoming S.T.A.L.K.E.R.: Call of Pripyat
will be a DirectX 11 game so those with the new AMD Radeon HD 5XXX cards
as well as Windows 7 will be able to take advantage of the new technology. In any case, the game's listed on their website
as coming in Q1 of 2010. I never played the previous games so if you have, is it worth it for me to spend some time on it?
