I skimmed bug #18490, and I'm wondering about two things: Does the app create 
a D3DDEVTYPE_REF or D3DDEVTYPE_NULLREF device? Once the device is created, 
what does it to with it? A +d3d log would provide some answers.

This is some guesswork: I don't think the game creates a _REF device because 
REF devices require the user to install the reference rasterizer dll, as 
Matteo already mentioned. If it's a NULLREF device I wonder what the game is 
able to do with it. The bug report has a link which promises some clues, but 
the link is dead.
