How to enable DirectX 10?

[Saotoshi]

Hey, I want to activate this last Option in Graphics options, which requires the game to use DirectX 10, but for some reason it is greyed out, tried everything I could find so long on the Internet, like start commads in Steam or Compatibility Mode, nothing. Can you guys help me please?

Make sure your hardware can actually handle dx10, most systems made in the last 6-7 years
should be able to. go to the steam launch options for this game and type in "-dx10" (minus the
quotes). You can also set dx10 in the options menus in-game. You'll also need to see my post here:

Other things you can try:

1. Update your video drivers.
2. Set compatibility to windows 7
3. Set the bioshock 2 executable to run in administrator mode.


Once you have dx10 running, you might have issues with the game crashing, that's what
my post is about, you'll have to uninstall a platform update to get it running properly.

If you try everything and dx10 mode still crashes, you'll have to go back to dx9 mode.
