The game checks if D3DDEVCAPS_HWTRANSFORMANDLIGHT flag is set in the 
device enumeration callback.
If it is the case, the games fails saying there is no D3D device found.
After all the enumeration, it checks the DRAWPRIMITIVE2EX flag. It it is 
not set it fails saying that the device is not
DX7 compliant.
