Hello folks,

confirming.
The stub for D3D11CreateDevice() is not enough.

"needs DX10/11 compatible hardware and DX11 runtime"

You can force the game to use specific D3D_FEATURE_LEVEL through additional
command line arguments.
Arguments that are recognized by game code:

-d3d10 or -sm4 (shader model 4)
-d3d11 or -sm5 (shader model 5)
-forcePretendUserHasDX10Card
-d3ddebug

"-forcePretendUserHasDX10Card" actually forces use of D3D_FEATURE_LEVEL_10_0

But even if you request dx10 feature set, D3D11CreateDevice() will be still
used unconditionally.
I debugged the game - there is no d3d10.dll fallback (hence the DX11 runtime
requirement).

I quickly hacked something together, reusing D3D10CreateDevice code to return a
stubbed ID3D11Device and ID3D11DeviceContext.
This allows the game to overcome the initial checks (running much farther) but
ending up really wanting fleshed out ID3D11Device methods
(CheckFeatureSupport(), ...).
I stopped at this point ...

$ wine --version
