Bioshock 2 wont start in DX10 mode

[dwillingm]

I have Bioshock 2 through Steam. I am using Windows 7 64-bit with the newest nvidia drivers.

When I start the game it locks up in a black screen. When I Ctrl-alt-del to get out, it says Bioshock has stopped working.

To get the game to start up I must force dx9 mode (adding the -dx9 command to the exe).

How do I fix this to play in DX10 mode? I have already tried updating my DX from microsoft. dxdiag says I have DX10.

DX10 is being detected, otherwise Bioshock 2 wouldnt try to load in DX10 mode.

Also, I got a free copy of the original Bioshock from Steam, and it has the same problem.

What's your graphics card?

Not sure what the technical problem is, but i wouldn't worry about dx10. I have run in dx10 and dx9, and done many comparisons and I can see no real difference between the dx9 and dx10 graphics.

I have the same issue with a store bought copy, an 8600 GTS with Vista 32-bit and the latest drivers. when it finishes the starting cinematic, the sound cuts out and it hits a black screen.

I have GTX 260s in SLI.

DX10 has some sort of improved textures. It bothers me that I am not able to play in DX10, regardless of whether it makes a big difference or not.

Yeah, I know what you mean. It's frustrating that a game that just came out has this kind of glaring issue.

On my drop down menu it doesn't even mention dx10, on all my other games it does.

[cureforsanity]

Which drop down menu are you referring to?

bioshock 2 does not like d3doverrider to force triple buffering. i am using the d3doverrider that came with rivatuner 2.24c.

if d3doverrider is not forcing triple buffering in the bioshock 2 exe file, then the game will load up.
