shall i install direct9 or allow him to select the driver?

[omarb]

when creating my application.. shall i install Directx9 on the users computer along with it, or allow him to select the most suitable driver?
what is the best practice.. thanks

I think the best option in my opinion would be to let the user decide what driver to use. I suppose you could also try and start your program up with DirectX if createDevice returns null then try Opengl and so on.

hi,
i tried this: (as u notice i am using .net)
this is not crashing but i am getting a grey screen
Try
If device Is Nothing Then
device = New IrrlichtDevice(Irrlicht.Video.DriverType.OPENGL, New Dimension2D(c.Width, c.Height), 32, False, False, False, True, c.Handle)
End If
Catch ex As Exception
End Try
Try
If device Is Nothing Then
device = New IrrlichtDevice(Irrlicht.Video.DriverType.DIRECT3D9, New Dimension2D(c.Width, c.Height), 32, False, False, False, True, c.Handle)
End If
Catch ex As Exception
End Try
Try
If device Is Nothing Then
device = New IrrlichtDevice(Irrlicht.Video.DriverType.DIRECT3D8, New Dimension2D(c.Width, c.Height), 32, False, False, False, True, c.Handle)
End If
Catch ex As Exception
End Try

----------------------------
on this machine when i use this directly the application works:
device = New IrrlichtDevice(Irrlicht.Video.DriverType.OPENGL, New Dimension2D(c.Width, c.Height), 32, False, False, False, True, c.Handle)
any idea why that is happening?

Someone else more knowledgeable with .NET will have to help you with that code snippet.
