Hello, <br><br>I am trying to debug the demo of The Sting. Now, the main is that the screen is almost black. It is surely related to the following FIXME:  fixme:d3d7:IDirect3DDeviceImpl_7_ComputeSphereVisibility<br><br>Unfortunately, I did not find any informations about this function. Does anyone know what this function does, ( and better knows a possible implementation)?<br>
<br>Thanks,<br><br>David Adam<br>
