NVIDIA announced the upcoming UT3 game will be DirectX 10:
More good news, I just had lunch at Vesuvios here with Mark Rein and he confirmed that we can now come out and say that Unreal Tournament 3 will be DX10 and in "The Way Its Meant To Be Played" program for launch. We have a long standing and close relationship with Mark and the team at Epic. We're delighted to be able to confirm this. The official site for UT3 can be found here. Thanks to Bill Rehbock, the father of 'The Way Its Meant To Be Played' program for lunch.
