DX11 driver not working - Win 8.1

Nov 20, 2014 cellsafemode link
Running Windows 8.1 64bit latest Windows update patches applied.

Nvidia GTX 970M Driver 344.75

What happens is upon selecting the DX 11 renderer driver the screen turns black and nothing happens. Sound continues to play but application becomes unresponsive, even after waiting 15 minutes. It reverts back to DX9 driver upon force closing the program.

This is all that i could find in the way of errors. Basically the content of the DirectX11 file.

Try adding these lines to the end of your config.ini

[directx11]
windowmode=1

Make sure there's a blank line before the [directx11] line.

Ok, finally had some time to play with the config file.
You need to also manually edit the line that says which renderer to use. Simply adding the block you posted to the bottom and then changing the renderer in game causes the windowmode option to be set back to 0 by the game.

Once i set both in the config file correctly prior to running it ran, albeit in an fullscreen window that cut off items from the bottom of the screen but it ran just fine.

I got a fresh install of the game on Win7 x64 and this exact same thing is happening when switching from DX9 to DX11.

Windows 8.1 64bit, GTX 880M, nvidia driver 355.98 (and the previous ones), windowmode=0, dx11, switching to dx9 and back to dx11, no problem.

Yeah, sure it works when i go in and edit config.ini by hand, but that's not the point.

The point is, changing it in the in-game GUI is broken, and it makes the game seem broken. That's not really acceptable for a game that expects you to pay $10/mo to play.

ARF, what video card? and do you have the latest drivers?
And when dx11 fails, what is the contents of the directx11.log file?

That was my friend's home theater PC. He's got some AMD Richland-based APU system. I'll see if I can get some more details or log data for you.

We were trying to see if VO worked with his 3D television. I regret to report that the game won't even launch from TriDef Ignition.
