Windows Store Apps don’t accept command line arguments by default, so to pass them you have to call a special function from App.xaml.cs/cpp or App.cs/cpp. For ex., appCallbacks.AddCommandLineArg(“-nolog”); You have to call it before appCallbacks.Initialize() function.
-nolog - Don’t produce UnityPlayer.log.
-force-driver-type-warp - Force DirectX 11.0 WARP device (More info http://msdn.microsoft.com/en-us/library/gg615082.aspx)
-force-gfx-direct - Force single threaded rendering.
-force-d3d11-no-singlethreaded - Force DirectX 11.0 to be created without D3D11_CREATE_DEVICE_SINGLETHREADED flag.
