Failed to create D3D Device! -> Only window mode working!

Hi!
I installed the game right fine. But it is not working at all.
I got the d3d error everytime - even if i set the res in the launch options!
The only way to get it working is to run it in window mode (-window in launch options). Then i am able to play the game. When i run it in window mode and set the res to fullscreen then there is no error, but the screen keeps black.

hardware:

full updated asus n56vz

is there any fix for this problem?

You’re not the first to report this problem. It seems to be Optimus-related drivers issue. No fix (except for playing in windowed mode) known so far.
You could “workaround” it by using borderless windowed mode. Add following to BM command line parameters:

-windowed -noborder -x 0 -y 0 -width <your screen resolution width> -height <your screen resolution height>
