Hey guys, can anyone explain in detail why DX10 cannot be used in Xp? ive asked this question on another smaller forum before and got the reply that they completly re-desighned the graphics arctitecture or somethign along the lines of that but WHY? i realy realy want to go back to Xp,im so fed up with vista but its DX10 thats keeping me there. atm i only have 1 game thats DX10 which would be crysis and i hardly play it,infact i dont have it installed right now. im not sure if Brother in arms:Hells highway is DX10 or not? im just looking for more information to why DX10 is vista only? is it just microsofts way of forcing you to buy vista?
