You need Vista as your OS it works fine for me under Vista on a 4850 and looks incredible plus the FPS is much better something like 20-25% faster than an 8800GTX so very smooth gamplay.Hi I just installed bioshock on my pc but i noticed that the option for dirext x 10 is greyed out so i think its running in dx9.
i have a radeon 4850 and installed the recent driver update.
how do i get it to work in dx10?
DX10 Bioshock has better looking water everything else looks similar to DX9 mode.
I just checked dxdiag it says direct x version: 9.0c
So that means you cant get dx10 for xp?
